Abstract:The (002) directional Yttria-Stabilized Zirconia (YSZ) buffered layer film was deposited on the stainless steel substrate with the Ar+ ion beam assistence at room temperature,and then the YBa2Cu3O7-x (YBCO) film was deposited on the YSZ/stainless steel substrate at 750℃ by pulsed laser ablation. The experimental results show that the critical temperature and the critical current density of the YBCO superconducting film are 91 K (R=0) and 1.2×106 A/cm2 (77 K, 0 T) respectively.
Keywords:high current density YBCO tape  pulsed laser deposition  ion beam assistance  stainless steel substrate
