Easily Activated Flux Creep and Anisotropic Fluctuation in Ndcecuo Thin Films

Abstract

The diamagnetic properties of NdCeCuO films with electron carriers were studied. The,critical current density ( Jc ) was calculated to be 0.73 x 106 A/cm2 . These films indicated the very strong magnetic relaxation with small activation energy, the significant resistive broadening in the critical region and the largely fluctuated diamagnetization. These results suggested the very weak pinning forces to cause the easily activated flux motion in these specimens.
