Abstract

The laser ablation technique was used to fabricate high Tc superconducting composite structures. The multilayered structures were fabricated in‐situ by changing the target during deposition. Thin MgO films and yttrium‐stabilized Zr02 films were used as buffer layers. The composite films were successfully fabricated on ZrO2(100) substrates. There is negligible interdiffusion occurring at the interfaces and the Jc at 77K is higher than 105A/cm2 for YBCO films in a triple layered structure.
