Abstract
The Pb0.7Sr0.3[(Fe2/3Ce1/3)0.012Ti0.988]O3 (PSFCT) and Pb0.7Sr0.3[(Fe2/3La1/3)0.012Ti0.988]O3 nanoparticles were prepared by chemical synthesis route using polyvinyl alcohol as surfactant. X-ray diffraction pattern has been used to analyze the phase structure and average particles size. The phase structure is also confirmed by Raman spectra. The chemical states of Pb2+, Sr2+, Fe3+; Ti4+, Ce3+, La3+, and oxygen ions have been analyzed by X-ray photoelectron spectroscopy. The magnetoelectric coupling effect is confirmed by magnetic phase transition near ferroelectric phase-transition temperature. The magnetoelectric effect is also confirmed by measuring the value of magnetoelectric coefficient (αE) as the function of applied dc magnetizing field under the influence of ac magnetic field of 10 Oe and frequencies of 847 and 997 Hz. The higher value of αE is observed in PSFCT sample.
