FORMATION OF SUPERCONDUCTING (TI,BI)SR2CACU2OY THIN-FILMS BY RF-SPUTTERING AND THALLIUM DIFFUSION
We have prepared new high Tc superconducting thin films of (Tl,Bi)-Sr-Ca-Cu-O by combining low temperature (500 °C) rf sputtering of Bi-Sr-Ca-Cu-O precursor films and thallium diffusion. A typical film has T c(onset) =80 K, Tc(midpoint) =79 K, and T c(zero) =50 K. X-ray diffraction and energy disper...
