摘要

Thin films of Bi-Ca-Sr-Cu-O were prepared by rf magnetron sputtering a sintered Bi2CaSr2Cu2O8-y target. The films were deposited on a MgO(100) substrate. The data reported here have a Tc (50%) of about 86 K and a transition width Tc=9081 K (9010%). Temperature-dependent I-V characteristics examined over wide ranges reveal that the critical current is proportional to (1-T/Tc)3/2 near Tc. The implication of the (3/2 power dependence will be discussed.
