Abstract: Ni nanoparticle-added Nix/(Cu0.5Tl0.5)Ba2Ca2 Cu3O10-δ superconductor composites are synthesized at normal pressure by two-step solid-state reaction method. The idea for adding ferromagnetic nanoparticles was to create artificial pinning centers at grain boundaries. The samples have shown… read more here.

Abstract: Ferromagnetic nickel (Ni) nanoparticles were added in (Cu0.5Tl0.5)Ba2Ca2Cu3O10–δ (CuTl-1223) superconducting matrix to get Nix/CuTl-1223; x = 0–1.00 wt% nanoparticles-superconductor composites. Temperature- and frequency-dependent dielectric properties of CuTl-1223 superconducting phase with different contents of Ni nanoparticles were studied.… read more here.
