Abstract
High Tc Sr–La–Cu–O and Ba–Y–Cu–O thin films have been successfully prepared by the magnetron sputtering method. The Tc onsets for Sr–La–Cu–O are 25–30K and Δ Tc are 7.5–8.5K. The slope near Tc is 3.05T/K. The Tc onsets of Ba–Y–Cu–O thin films are 87–89.5K and the zero resistance is at 20K. The samples are diamagnetic and the Meissner effect appeared around 10K.Keywords
