We have formed BaZrO 3 nanocolumns and (Gd, Y) 2 O 3 nanoprecipitates in reel-to-reel
metal organic chemical vapor deposition (MOCVD) processed (Gd, Y) Ba 2 Cu 3 O 7− x …

Addition of pyrochlore rare earth tantalate phases, RE 3 TaO 7 (RTO, where RE= rare earth,
Er, Gd and Yb) to YBa 2 Cu 3 O 7− δ (YBCO) is shown to vastly improve pinning, without …

Fe-based superconductors bridge a gap between MgB 2 and the cuprate high temperature
superconductors as they exhibit multiband character and transition temperatures up to …

The thickness dependence was studied for the critical current density (J c) of YBa 2 Cu 3 O
