Observation of τ Lepton Pair Production in Ultraperipheral Pb-Pb Collisions at sqrt[s_{NN}]=5.02 TeV.

We present an observation of photon-photon production of τ lepton pairs in ultraperipheral lead-lead collisions. The measurement is based on a data sample with an integrated luminosity of 404 μb^{-1} collected by the CMS experiment at a center-of-mass energy per nucleon pair of sqrt[s_{NN}]=5.02 TeV. The γγ→τ^{+}τ^{-} process is observed for τ^{+}τ^{-} events with a muon and three charged hadrons in the final state. The measured fiducial cross section is σ(γγ→τ^{+}τ^{-})=4.8±0.6(stat)±0.5(syst) μb, where the second (third) term corresponds to the statistical (systematic) uncertainty in σ(γγ→τ^{+}τ^{-}) in agreement with leading-order QED predictions. Using σ(γγ→τ^{+}τ^{-}), we estimate a model-dependent value of the anomalous magnetic moment of the τ lepton of a_{τ}=0.001_{-0.089}^{+0.055}.

Modulated Optoelectronic and Magnetic Properties of Mn‐Doped SrTiO3: A Density Functional Theory Insight

Herein, the substitution of Mn in SrTiO3 is presented as an effective approach to develop functional ferromagnets with spin‐polarized semiconductive band dispersions. The task is performed with the full‐potential linearized augmented planewave (FP‐LAPW) approach based on density functional theory (DFT) as coded in WIEN2k. Exchange and correlation effects are taken into account using generalized gradient approximation (GGA). The strong hybridization between O‐2p and Mn‐3d is accountable for the origin of the semiconductive ferromagnetic ground state in Sr1−xMnxTiO3 (x = 12.5%, 25%, 50%, and 75%). Increase in Mn content in SrTiO3 crystal causes a significant increase in total magnetic moment values. The optical behavior is investigated by computing refractive index, optical conductivity, dielectric constant, absorption coefficient, and reflectivity within 0–10 eV energy range. Mn‐doped SrTiO3 shows maximum absorption in the ultraviolet region. The computed physical characteristics suggest a potential usage of Sr1−xMnxTiO3 in optoelectronic and magnetic devices.

Thermodynamic, thermoelectric and optoelectronic performances of Co2MB (M = Nb, Ta) full-heusler compounds for solar cell and UV absorber applications

An investigation for estimating the thermodynamic, thermoelectric and optoelectronic performances of Co2MB (M = Nb, Ta) full-Heusler compounds is accomplished via density functional theory within full-potential linearized augmented plane wave (FP-LAPW) method. The generalized gradient approximation (GGA), GGA + U (Hubbard correction), Tran-Blaha modified Becke-Johnson potentials (TB-mBJ) and spin-orbit coupling (SOC) are utilized to handle the exchange and correlation potential. The electronic band structure of Co2NbB and Co2TaB confers half-metallic nature over reasonable band gaps; 0.71 and 1.11 eV, respectively within mBJ potential. The materials are manifested with the integer values of spin magnetic moment. Further, various thermodynamic parameters under the effect of temperature and pressure have been assessed. Interestingly, Co2NbB and Co2TaB exhibit fantastic thermoelectric performances concerning high figure of merit at 1200 K. Furthermore, the computed materials are optically active and display absorption spectra in visible and more significantly in UV region of incident light. Therefore, materials can be used as good UV absorbers.

Investigation on the physical properties of Ni doped SrTiO3 by first-principle calculations

In present work, the magneto-electronic and optical features of Sr1-xNixTiO3 (x = 12.5%, 25%, 50% and 75%) compounds are calculated using full potential linearized augmented plane wave (FP-LAPW) scheme within density functional theory (DFT) as employed in WIEN2k software. The electronic band structures (BS) and density of states (DOS) interpret the induced half metallic ferromagnetism mainly originating from highly spin polarized Ni-d states. The computed value of total magnetic moment of Sr1-xNixTiO3 is 1.99998, 1.99991, 2.00003 and 2.00005 µB at 12.5%, 25%, 50% and 75% concentration respectively, which emerge primarily due to Ni-3d electrons. Furthermore, the optical features (refraction, dielectric function, absorption, and reflectivity) have also been computed within energy range of 0-10 eV. Sr1-xNixTiO3 is optically active in visible to ultraviolet (UV) region owing to low reflectivity and high absorption. Results portray that the studied compound is a potential contender for its usage in the development of spintronic and optoelectronic devices.

Enhanced dual superconducting and ferromagnetic properties of YBCO film tuned with boron and oxygen partial pressures

This study reports the dual enhancement of superconductivity and ferromagnetic properties of YBCO films for the first time. These dual enhanced properties have been achieved by tunning YBCO films with dopant boron and oxygen partial pressures. Thin films of YBa2Cu3-xBxO7-y with different B concentrations and oxygen partial pressures were fabricated by electro-spin coating. The systematic optimization of B concentration and oxygen partial pressure of YBCO films were studied through microstructural, electrical, optical, and magnetic properties. In particular, YBCO film doped with 20 mol% B and 20 SCCM O2 pressure showed excellent superconducting and magnetic properties. The breakthrough of this study in the films YBa2Cu2.4B0.6O7−y/20 SCCM, not only displayed enhanced superconducting properties but also ferromagnetic properties at near transition temperature (Tc) (i.e., 109 K). The magnetic moment values YBa2Cu2.4B0.6O7−y/20 SCCM films achieved ≈ 0.65 μB/mol, which is two order increment of films prepared without oxygen partial pressure. The dopant boron and oxygen partial pressure provide a new pathway for tuning the superconducting and ferromagnetic properties of YBCO thin films.

Non-stoichiometric ErFe2Mnx compounds: Structure, magnetic, magnetoelastic and magnetothermal properties

Crystal structure, magnetostriction, magnetic and magnetothermal properties have been studied for novel non-stoichiometric ErFe2Mnx (0 ≤ x ≤ 0.6) compounds. It has been found that for х ≤ 0.4 the compounds crystallize with MgCu2-type structure. Curie temperature and magnetic moment values decrease with manganese alloying. Molecular field coefficients have been calculated within ferrimagnetic two-sublattice molecular field model. Magnetic and heat capacity measurements have been used to calculate magnetocaloric effect in a wide temperature range. It has been demonstrated that increasing the Mn content in ErFe2Mnx leads to a significant increase (up to 39 %) of anisotropic magnetostriction value at 77 K in magnetic field of 18 kOe. At the same time, the value of effective magnetocrystalline anisotropy decreases. Thus, manganese alloying opens new way for tuning magnetocrystalline anisotropy and magnetostriction in Laves phase compounds.

Analysis of Structural Stability and Half-Metallic Ferromagnetism of Cs2VX6 (X=Cl, Br) Double-Perovskites for Spintronic Applications: Ab-Initio Simulations

Spintronics has become an emerging field based on electronic spin usage for various technological applications. Herein, we explored the ferromagnetic characteristics of novel double-perovskite Cs2VX6 (X=Cl, Br) compounds within the framework of density functional theory. In search of the most stable ground state, we found the ferromagnetic state is at the lowest possible energy state. The structural stability in the cubic phase was assessed from the Goldschmidt tolerance factor, and negative values of formation energies confirmed thermodynamic stability for both compounds. The existence of all positive frequencies in phonon spectra indicates both compounds are thermodynamically stable, and their spin-polarized density of states and band structures revealed the half-metallic ferromagnetism nature. The 100% spin polarization factor and the reasonable magnetic moment values suggest these double-perovskites potential in spintronic applications. Additionally, the thermoelectric response, regarding high power factors suggests these double-perovskites suitability for thermoelectric device applications.

Inference and visualization of nuclear magnetic moment studies with neuro-fuzzy systems

This study aims to predict the magnetic moments of nuclei with odd-A numbers in a certain region of which the magnetic moment has not yet been calculated, using the Adaptive Neuro-Fuzzy Inference System (Anfis) method. In our Anfis model the proton number (Z), neutron number (N), and spin value (I) are used as inputs for nuclei with 1 ≤ Z ≤ 88. With 652 nuclei in the dataset, consisting of the provided input data, 528 odd-A nuclei were used for training, and 124 odd-A nuclei were used for testing. The fact that the Anfis model was closer to the experimental data in the training and testing processes than the theoretical methods encouraged us to make inferences about the nuclei of which experimental nuclear magnetic moment is unknown. Motivated by the presence of odd-A nuclei exhibiting I π = 1/2±, 3/2±, and 5/2± ground-state configurations near the doubly closed-shell, within the 1 ≤ Z ≤ 28 regions, along with the limited knowledge of nuclear properties in this range. This study has conducted magnetic moment inferences for 165 nuclei lacking experimental data. Specifically, Na, F, and P isotopes have been chosen as Magnetic moment value inferences made for these isotopes using Anfis have also been compared with the theoretical results of the Quasiparticle-Phonon Nuclear Method (QPNM) and with the Shell Model calculations. There is a satisfactory agreement between our predictions and the results of these two theories. Furthermore, it is noteworthy that within the same isotope series, nuclei with identical ground-state configurations consistently yield compatible results, irrespective of the availability of experimental magnetic moments. In addition, the fact that the values obtained from test and train operations remain within acceptable error limits, with a range of approximately 0.03%–0.04%, reveals the reliability of our system. Since the Neuro-Fuzzy system will be a first in the field of nuclear technologies, we believe that the outputs of our study will be a good reference for future studies.

A comprehensive DFT study on the physical properties of XCrAl (X= Fe, Co, Ni, Cu) half-Heusler alloys for applications in high-temperature technology

In the present work, structural, electronic, magnetic, elastic, mechanical, thermal and optical properties of XCrAl (X = Fe, Co, Ni, Cu) Half-Heusler (H–H) alloys were explored. First-principles study based on the non-polarized and spin-polarized density functional theory (DFT) were employed to get the geometrically relaxed unit cell structures of H–H alloys of investigation. The larger lattice constant values were found due to the spin polarization and the magnetic moments were calculated from the spin density of states (DOS). The higher values of magnetic moments make XCrAl alloys suitable for magnetic device applications. The computational electronic structure analyses at zero applied pressure confirm the zero energy band gap of XCrAl alloys which displayed metallic nature for all the compounds. From the elastic constants calculations, all the studied alloys were found mechanically and thermally stable. The values of melting temperatures were obtained in the range from 2072 to 1883 K and the calculated Debye temperatures followed the same manner of variation. Among the studied compounds, FeCrAl exhibits highest melting temperature and lattice thermal conductivity with the value of 12.94 Wm−1K−1 at 300 K which is in good agreement with the other reported results. These investigations suggest that, FeCrAl is relatively more suitable in accident-tolerant fuel (ATF) cladding material applications over the common Zr-based cladding rods. The frequency dependent optical properties of the studied H–H alloys were also explored comprehensively and the examinations indicate that, XCrAl (X = Fe, Co, Ni, Cu) alloys can also be the good choice for ultraviolet (UV) based optical device applications as they have high absorption coefficient of >200 × 104 cm−1 and maximum reflectivity of >94% in the UV region.

Crystalline Rhodium‐Tin Complexes with Radical Trianion and Tetraanion Phthalocyanine Ligands: Observation of Nimine(Pc)−Rh Coordination Bond

AbstractCrystalline {Cryptand(Na+)}[(COD)RhICl⋅SnII(Pc3−)]−⋅2C6H4Cl2 (1) and {Cryptand(Cs+)}[(COD)RhI⋅SnII(Pc4−)]−⋅C6H5CH3 (2) complexes were obtained via the interaction of [SnII(Pc3−)]− and [SnII(Pc4−)]2−, respectively, with organometallic {(COD)RhCl}2 dimer (COD is 1,5‐cyclooctadiene). Dissociation of {(COD)RhCl}2 followed by the Rh−Sn binding is observed at the formation of 1. Elimination of the chlorine atom at the rhodium atom is observed in 2, and rhodium is additionally coordinated to the imine nitrogen atom of Pc4−. The complexes contain mono‐ Pc⋅3− and doubly reduced Pc4− species, respectively, that is supported by the data of XRD analysis as well as optical and magnetic properties of 1 and 2. There is an alternation of C‐Nimine bonds in the macrocycles, which gradually increases with increasing negative charge on the macrocycle. The difference between shorter and longer bonds increases from 0.051 Å in Pc3− to 0.075 Å in Pc4−. The formation of 1 is accompanied by an essential blue shift of the Q‐band of starting SnPc and the appearance of a new intense band at 1031 nm. The even stronger shift of the Q‐band is observed in the spectrum of 2, but the band in the near‐IR range becomes weaker. The value of effective magnetic moment of 1 is 1.76 μB at 300 K corresponding the contribution of the Pc3− radical trianions (S=1/2). Only weak magnetic coupling with the Weise temperature of −3 K is observed in 1 due to weak π–π interaction between the macrocycles in the chains. Paramagnetic Pc3− species additionally monitored by EPR spectroscopy show a strong temperature dependence of g‐factor and linewidth of the EPR signal. Complex 2 is diamagnetic and EPR silent.

Half metallicity and optical properties of Ba2B′ReO6 (B′ = Cd, Er): a DFT insight

Barium based double perovskite rhenates are being comprehensively studied due to their diverse magnetic behaviors, extending from ferri- to (anti) ferro-magnetism which is mostly influenced by theoretical Hubbard interaction parameter (U). Therefore, density functional theory (DFT) and U are brought together to reveal the origin of half metallicity with ferromagnetic ordering in Ba2CdReO6 and ferrimagnetism in Ba2ErReO6. The precise estimation of exchange correlation energies has been performed with generalized gradient approximation (GGA). In both compounds, the 100% spin polarization at Fermi level arises primarily due to Re-d orbitals and minute involvements from respective Cd/Er cation’s valence orbitals along with total magnetic moment values of ∼1.0 μ B . Moreover, in optical response, ample amount of absorption and optical conductivity is observed in the UV region of both DPs. The thermo-structural stability of Ba2B′ReO6(B′ = Cd, Er) along with 100% spin polarization and superior optical properties make these DPs the potential candidate for various spin-optoelectronic devices e.g., spintronic devices and optical filers.

Neutrino spin-flavour precession in magnetized white dwarf

Due to notoriously small value of the neutrino magnetic moment, the phenomena of neutrino spin flavour precession (SFP) require a very high magnetic field. This makes only a handful of systems suitable to study this phenomenon. By the observation of SFP, the Dirac and Majorana nature of neutrinos is expected to be distinguished. In this work, we point out the potential of the white dwarf (WD) system in studying the spin-flavour oscillation of neutrinos. From recent analysis, it has been found that young isolated WDs may harbour very strong internal magnetic field, even without exhibiting any surface magnetic field. The presence of a magnetic field enhances the cooling process and along with that, renders the spin-flavour oscillation of neutrinos emitted in the neutrino cooling process. Employing the standard WD specifications, we analyse whether a magnetized WD is a suitable environment to distinguish between the Dirac and Majorana nature of the neutrino. Higher value of spin flavour transition probability implies reduced active neutrino flux which is possible to be estimated in terrestrial neutrino detectors. We find that for the current upper bound on the neutrino magnetic moment, the spin flavour transition probability of Dirac neutrinos is much higher in comparison to the Majorana neutrino which converts the active neutrino flavours to sterile in a significant amount. We also examine the sensitivity of the spin flavour transition probability to the neutrino magnetic moment.

Magnetic properties of the FCC and BCC phases of (MnFeCoNi)80Cu[formula omitted] ([formula omitted]: Al, Ga) high-entropy alloys

In this work, the FCC-BCC phase transition in (MnFeCoNi)80Cu20−xZx (Z: Al, Ga) high entropy alloys were investigated on the basis of structural, magnetic, hardness and thermal expansion properties. It is found that the equiatomic MnFeCoNiCu alloy is FCC and exhibits mixed ferromagnetic/anti-ferromagnetic interactions with a Curie temperature, Tc, close to room temperature. However, the BCC structure emerges with increasing amount of Al (10 at%) and Ga (15 at%) with additional ferromagnetic interactions and associated Tcs. It is evidenced that in terms of the valence electron concentration and the average magnetic moment values, the investigated HEAs obey the Slater-Pauling rule in a region close to the Heusler alloys. Additionally, they may exhibit similar physical properties like Invar property with low thermal expansion coefficient with the 3d-transition metal-alloys having same valence electron concentration.

Phase stability and physical property for off-stoichiometric Ni-Mn-Sb alloys including 4O phase

Large magnetic field-induced strains can only be found in modulated martensite for Ni-Mn-Sb alloys, but the theoretical research on this alloy which is generally concentrated in the austenite and non-modulated martensite (NM) ignores the modulated martensite. Therefore, in this paper, we systematically study the relationship between phase stability, physical property and composition in the full series Ni-Mn-Sb Heusler alloys (Ni24+xMn12-xSb12, Ni24+xMn12Sb12-x, Ni24-xMn12+xSb12, Ni24Mn12+xSb12-x) including four-layered orthorhombic modulated martensite (4O) by the first principles calculations. For phase stability, we determined that the critical components of 4O for Ni24+xMn12-xSb12, Ni24+xMn12Sb12-x and Ni24Mn12+xSb12-x is × = 6, x = 6 and × = 4, respectively. There is no 4O phase within the concentration range considered for Ni24-xMn12+xSb12. Moreover, the martensitic transformation sequences are also determined. As for physical properties, the transformation temperatures from austenite to 4O and NM phases are predicted respectively. Meanwhile, the ternary magnetic moment diagram of austenite, 4O and NM phases is constructed. The maximum value of total magnetic moment is distributed in the Ni-excess Sb-deficient system, while the minimum value of that is distributed in the Mn-excess Sb-deficient system. The origin of the above observations is explained by the competition between the Jahn-Teller effect in the electronic structure and the strength of the covalent bond. The results in this paper are expected to provide information for the composition design and performance optimization of Ni-Mn-Sb alloy.

First-principles calculations to investigate structural, electronic and magnetic anisotropy energy of ZnFe[formula omitted]O[formula omitted] spinel ferrite for spintronics applications

Structural, electronic and magnetic investigations of ZnFe2O4 have been made by using density functional theory with Perdew–Burke–Ernzerhof Generalized-Gradient Approximation as exchange and correlation functional. Additionally, the effect of Hubbard, U, and spin orbit coupling, SOC on electronic and magnetic properties has also been observed. The U-value for Zinc and Iron are used, 6.0 eV (0.44 Ry) and 4.3 eV (0.316 Ry) respectively. The optimized lattice parameter matches well with experimental with mere percentage difference of 0.039%. This optimized lattice constant is used for SCF calculations to calculate the above mentioned properties of zinc ferrite. It is found that zinc ferrite have high value of magnetic moments, 19.721μB, 20.003μB, and 19.580μB for PBE, PBE with Hubbard, and with spin orbit coupling respectively. The magneto crystalline anisotropy energy calculations confirm the utility of this material for spintronics device fabrication.

Magneto-structural characterization of different kinds of magnetic nanoparticles

Using well-established measurement techniques like transmission electron microscopy (TEM), dynamic light scattering (DLS), small and wide angle X-ray scattering (SAXS, WAXS), susceptometry, and magnetorelaxometry, the distribution of the physical and magnetic size (magnetic moments) and magnetic anisotropy of a variety of structurally different magnetic nanoparticle samples (MNPs) is analyzed and compared. A term which accounts for the presence of weak magnetic areas (WMAs) within the MNPs was introduced to the widespread analysis model for M(H) data, enabling a consistent interpretation of the data in most of the systems. A comparison of the size distributions as obtained for the physical and the magnetic diameter suggests a multidomain structure for three single core systems under investigation, in all probability evoked by the presence of a wustite phase, as identified by WAXS.Analyzing the relationship d < dm < dc between the average single core diameter d, the effective magnetic (domain) size dm and the cluster diameter dc quantitatively, two qualitatively different magnetic structures in multicore MNP (MCMNP) systems were identified: (i) The magnetic moments of single cores within the MCMNP of fluidMAG tend to build flux closure structures, driven by dipole–dipole interaction. (ii) The magnetic behavior of Resovist® was attributed to the presence of domain sizes of about 12 nm within MCMNP, exceeding the single core diameters of 5 nm. Thereby, WAXS revealed a bimodal crystallite size distribution suggesting a crystallite merging process within the MCMNP. The value of the effective magnetic moment of these MCMNP could be explained within the presented “random moment cluster model” (RMCM).We conclude that the combination of physical and magnetic structure parameters obtained from complementary measurement methods allows a reliable assessment of the magnetic structure of single and multicore MNPs.

Large ordered moment with strong easy-plane anisotropy and vortex-domain pattern in the kagome ferromagnet Fe3Sn

We report the magnetic anisotropy of kagome bilayer ferromagnet Fe3Sn probed by the bulk magnetometry and magnetic force microscopy (MFM) on high-quality single crystals. The dependence of magnetization on the orientation of the external magnetic field reveals strong easy-plane magnetocrystalline anisotropy and anisotropy of the saturation magnetization. The leading magnetocrystalline anisotropy constant shows a monotonous increase from K1≈−1.0×106 J/m3 at 300 K to −1.3×106 J/m3 at 2 K. Our ab initio electronic structure calculations yield the value of total magnetic moment of 7.1 μB/f.u. and a magnetocrystalline anisotropy energy density of −0.57 meV/f.u. (−1.62×106J/m3) both being in reasonable agreement with the experimental values. The MFM imaging reveals micrometer-scale magnetic vortices with weakly pinned cores that vanish at the saturation field of ∼3 T applied perpendicular to the kagome plane. The observed vortex-domain structure is well reproduced by the micromagnetic simulations, using the experimentally determined value of the anisotropy and exchange stiffness.

Evidence of weak itinerant ferromagnetism and Griffiths like phase in MnFeGe

Realizing the itinerant type of magnetic exchange in Mn-based alloys is quite unusual because of the weak hybridization between Mn-moments and conduction electrons. However, in the current study, we found MnFeGe to exhibit weak itinerant type magnetic character possibly arising due to the hybridization between Mn, Fe atoms with Ge atoms. Here, we present a comprehensive structural and magnetic study on polycrystalline MnFeGe. Rietveld refinement of the XRD pattern confirms that Mn and Fe atoms randomly (atomic disorder) occupy the 2a and 2d sites in MnFeGe. From the magnetic measurements, Curie temperature and saturation moment values are found to be 162 K and 1.58 at 2 K, respectively. The relative low values of Curie temperature, saturation magnetic moment, and a large value of Rhodes–Wohlfarth ratio (∼3.4) indicate the weak itinerant ferromagnetic character of the system. The Takahashi spin fluctuation theory analysis further supports the weak itinerant ferromagnetism in MnFeGe. Besides, we also observed Griffiths phase (GP) like behavior above the Curie temperature, which is attributed to the presence of atomic disorder in the system. The presence of GP is further confirmed by the zero spontaneous magnetization. Our findings demonstrate that MnFeGe is one of the very few Mn-based systems with weak itinerant magnetic behavior.

Magnetic Properties of CuCr1−xLaxS2 Thermoelectric Materials

The magnetic properties (magnetic susceptibility, magnetic moment) and Weiss constant for lanthanum-doped CuCr1−xLaxS2 (x = 0; 0.005; 0.01; 0.015; 0.03) solid solutions were studied using static magnetochemistry at 80–750 K. The samples were characterized by both powder X-ray diffraction and energy-dispersive X-ray spectroscopy. It was shown that synthesized samples are single-phased up to x ≤ 0.01. The presence of the additional phase in the solid solutions with x &gt; 0.015 caused deviation from the simple isovalent Cr3+→Ln3+ cationic substitution principle. It was found that magnetic susceptibility and the Weiss constant are significantly affected by both magnetic properties and lanthanum concentration for the solid solutions doped up to x = 0.01. The largest magnetic moment value of 3.88 µB was measured for the initial CuCrS2-matrix. The lowest value of 3.77 µB was measured for the CuCr0.99La0.01S2 solid solution. The lowest Weiss constant value of −147 K was observed for the initial matrix; the highest one was observed for CuCr0.99La0.01S2 (−139 K). The largest Seebeck coefficient value of 373 µV/K was measured for CuCr0.985La0.015S2 at 500 K; the obtained value was 3.3 times greater compared to the initial CuCrS2-matrix. The field dependence of the magnetic susceptibility allowed one to conclude the absence of ferromagnetic contributions in the total magnetic susceptibility of CuCr1−xLaxS2. The data on magnetic properties can be successfully utilized to investigate the limits of doping atom suitability and order–disorder phase transition temperature in CuCrS2-based solid solutions.
