Abstract

Thin films of the Y₁Ba₂Cu₃O_x superconductor have been grown by coevaporation and postannealing in oxygen on substrates of (100) SrTiO₃, (100) MgO, and (100) yttria-stabilized zirconia. Films grown on SrTiO₃ show evidence of both a- and c-axis growth normal to the substrate and strong in-plane order. Films on MgO show c-axis growth without any in-plane order, indicative of fiber texture. Transition temperatures of the films on MgO are depressed compared to those on SrTiO₃, but by using higher postanneal temperatures it is possible to improve the superconducting behavior of MgO samples
