Year: 1990
Type: article
Abstract: The effect of growth temperature on superconducting phases has been studied for BiSrCaCuO thin films grown on MgO(100) substrates at temperatures in the range 500–660°C by RF magnetron sputtering from three targets. The chemical compositions of the metal elements of the films formed at each substrate temperature were adjusted to Bi:(Sr+Ca):Cu=2:3:2, 2:3.5:2.5 and 2:4:3. Low-T c phases (232 phases), 232/243 phases and high-T c phases (243 phases) were obtained above 580°C with the 2:3:2 composition, above 590°C with the 2:3.5:2.5 composition, and above 620°C with the 2:4:3 composition.
