Formation of As-Deposited Y-Ba-Cu-O Superconducting Film by a High Temperature Spray Pyrolysis Method

Abstract

An as-deposited Y-Ba-Cu-O superconducting film of which thickness was 7 µm was prepared by a spray pyrolysis method without post-annealing procedure. This film showed T conset at 93 K and T cend at 25 K. Its surface was smoother than that of a film heat treated at 950°C after the spraying process.
