Transport in Oxide Superconductors
15 March 1988
Resistivities rho(T) of ceramic samples of La sub 1.825 Sr sub 0.175 CuO sub 4 (LSCO) and both ceramic and single-crystalline (a-b plane, containing micro- twins) samples of YBa sub 2 Cu sub 3 O sub 7-delta (YBCO) were measured from the respective transition temperatures T sub c to T = 1100K. Above room temperature measurements were performed in a flowing-O sub 2 furnace.
