SUPERCONDUCTIVITY AT 89K OF Ba-Y-Cu-O THIN FILMS
-
Abstract
High Tc Ba-Y-Cu-O thin films have been successfully prepared by the RF magnetron sputtering method. The highest Tc onset is determined to be 89.5K and the Tc midpoint is about 55K. Inductive measurement showed that the samples are diamagnetic and the Meissner effect appeared around 10K.
