In this work, we investigate the effect of NiO nanoparticles' addition on the structure, superconductivity, and magneto conductivity for the SmBa2Cu3O7-δ phase. Composite nano/superconductor of (NiO)x/SmBa2Cu3O7-δ (0.00≤x≤0.12 wt.%) were prepared by conventional solid-state reaction technique and characterized by X-ray powder diffraction (XRD) and scanning electron microscopy (SEM). The orthorhombic structure was maintained whereas the lattice parameters showed unsystematic variations with the NiO nanoparticles addition. The superconducting transition temperature Tc, determined from electrical resistivity measurements, showed an enhancement with x up to 0.04wt.% followed by a reduction …
