Effect of BaSnO3 Nanoparticle Inclusion on Critical Current Density of GdBa2Cu3O7-Thin Films

Effect of BaSnO3 (BSO) nanoparticle inclusion on the critical current density of GdBa2Cu3O7-x (GdBCO) thin films was investigated. BSO nanoparticles were prepared on a thin GdBCO seed layer of < 50 nm thick by using pulsed laser deposition (PLD) technique. The GdBCO superconducting layers were de...
