Abstract
In the present work, YBCO superconductor and their nanocomposite with MnO (YBCO:MnO(1%)) were synthesized using solid state reaction method. The orthorhombic phase formation of YBCO superconductor and after adding of MnO in the YBCO:MnO(1%) nanocomposite confirm by X-ray diffraction (XRD) patterns, there is no change in the crystal structure of YBCO. Scanning Electron Microscopy (SEM) analysis confirms the morphology of microstructure and Energy Dispersive X-Ray (EDX) spectra confirms the elemental identification of pure YBCO superconductor and YBCO:MnO(1%) nanocomposites samples, respectively. No decrease in the critical temperature (Tc) of YBCO was observed after incorporation of MnO(1%) in YBCO. Magnetization vs. Magnetic field (M-H) measurement was also performed using PPMS. The increased value of critical current density of YBCO:MnO(1%) nanocomposite has been achieved compared to pure YBCO which has been attributed to enhanced flux pinning due to presence of Mn in YBCO matrix.
