Abstract

The effects of NiO nano particles addition in YBa2Cu3O7-δ (YBCO) superconductors had been investigated. YBCO superconductor powders were prepared by using high purity oxide powders via solid state reaction method. 0.01 - 0.05 wt.% of NiO nano particles were added into YBCO. The critical temperature (Tc) and transport critical current density (Jc) were determined by using four point probe method. The lattice parameters and morphology of the samples were characterized by X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM), respectively. Tc of YBCO increased from 84 K to 87 K with 0.02 wt.% of NiO nano particles addition. The addition on NiO nano particles have significantly enhanced transport critical current density of YBCO by acting as flux pinning centers. YBCO with 0.03 wt.% of NiO nano particles performed the highest Jc up to 1265 mA/cm2 among the NiO-added samples. However, excessive addition of NiO nano particles in YBCO caused degradation in Tc and Jc.
