The superconducting behavior of (Y/sub 1-//sub x/La/sub x/)Ba/sub 2/Cu/sub 3/O/sub y/ compounds for 0less than or equal toxless than or equal to1 was studied. It was found that T/sub c/ decreased with increasing La content. (Y/sub 1-//sub x/La/sub x/)Ba/sub 2/Cu/sub 3/O/sub y/ for 0less than or equal toxless than or equal to0.4, fired at 1050 /sup 0/C in air, shows onset temperatures above 90 K. Annealing (Y/sub 1-//sub x/La/sub x/)Ba/sub 2/Cu/sub 3/O/sub y/ at 300 /sup 0/C in O/sub 2/ enhanced the onset temperature above 70 K for all studied compositions (x = 0--1), and altered the crystal structure from tetragonal to orthorhombic.
