Abstract

High‐Tc superconducting Y‐Ba‐Cu‐O films were prepared on Mg0(100) substrate by MO‐CVD technique without post annealing. The highest Tc obtained was 85K. The film was made up of dense matrix and dispersed fine particles. The Y‐Ba‐Cu composition of matrix was nearly equal to the 1:2:3 superconducting phase. The film was highly oriented with c‐axis perpendicular to the substrate. The lattice constant of the film was 11.68A.
