Abstract

In this work, we investigate the effect of NiO nanoparticles' addition on the structure, superconductivity, and magneto conductivity for the SmBa₂Cu₃O_7-δ phase. Composite nano/superconductor of (NiO)_x/SmBa₂Cu₃O_7-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 T_c, determined from electrical resistivity measurements, showed an enhancement with x up to 0.04wt.% followed by a reduction with higher NiO additions. The Aslamazov–Larkin (AL) model was employed to analyze the magneto conductivity. The model allowed to determine the coherence lengths along c-axis ξ_c(0) and along ab plane ξ_ab(0). Moreover, the anisotropy parameter Г increase with the increase of NiO nanoparticles addition.
