Y-Ba-Cu-O Superconducting Thin Films Prepared by Flash Evaporation

Abstract
Superconducting thin films of Y-Ba-Cu-O oxides were prepared by a simple technique of flash evaporation. The critical temperature T c(R=0) was 80 K in a ∼1 µm-thick film on a MgO substrate. The film showed a preferred c-axis orientation after annealing at 900°C and 600°C in oxygen.
