Description
Thin films of the Bi2(Sr/sub 1-//sub x/Ca/sub x/)/sub n//sub +1/Cu/sub n/O/sub y/ (n = 2, 3) system were prepared on (100)MgO substrates by coevaporation of Bi2O3, Sr-Ca alloy, and Cu metal. The lattice constant of the c axis of the low T/sub c/ (∼85 K) phase (n = 2) decreased with increasing Ca composition x. The superconducting transition temperatures of both the low T/sub c/ phase and high T/sub c/ (∼110 K) phase (n = 3) decreased with increasing x. These tendencies indicated that both the low T/sub c/ phase and the high T/sub c/ phase have a mutual solubility between Ca and Sr atoms in this Bi system and that the T/sub c/ 's of these two phases are related to the c-axis lattice constant
