PROCESS OF MANUFACTURE OF THIN SUPERCONDUCTIVE FILMS Russian patent published in 1996 - IPC

FIELD: superconductive films. SUBSTANCE: at first film composed of mixture of components containing 39-40 mole per cent of BaCuO₂ and 60-61 mole per cent of CuO is deposited by laser spraying on Y₂Ba_2,32Cu_1,68O₇ substrate. Superconductive YBa₂Cu₃O_7-σ film is formed by firing as a result of reaction of these components with substrate in the presence of liquid phase. EFFECT: facilitated manufacturing process. 7 dwg, 1 tbl
