Description
We report the temperature T and magnetic field H dependences of the critical current density Jc for Bi2Sr2CaCu2O8+y (BSCC) films with preferred c- axis orientation. Jc(T,H) versus 1/T as a function of H showed abrupt changes below threshold temperatures Tt(H) which decreased with increasing H. Non-linear current I versus voltage V characteristics disappeared around Tt(H) with increasing T. The appearance of Tt(H) is discussed comparing with anomalies observed in ultrasonic measurements
