Improvement of critical current density in YBa2Cu3O7-δ superconductor added with Pr2O3 and graphene oxide

The effect of nanoparticle praseodymium oxides (Pr2O3) and graphene oxides (GO) addition on the critical current density, Jc of YBa2Cu3O7-δ was studied. Both nanoparticles added acted as pinning center to enhance the transport critical current density (Jc). YBa2Cu3O7-δ superconductor was prepared...
