Preparation of Superconductive YBa2Cu3O7-x Thick Films by the Rapid-Quenching Technique

Abstract

Thick films of YBa₂Cu₃O_7-x (e.g. 50 µm thick × 13 mm wide × 45 mm long) with maximum density were prepared by rapid quenching. For the film heat-treated at 950°C in air, superconductivity was realized with an onset temperature of 98 K and zero resistivity of 87 K.
