Abstract

We have observed the flux motion using Hall probe sensors that are placed on the surface of high quality Y-Ba-Cu-O and Gd-Ba-Cu-O disks 15 mm in diameter with 0.95 mm thickness with applying pulsed magnetic field. The peak value of the field was varied from 0.1 to 0.8 T. The effects of static bias fields was also studied in the field range of 0-3 T at 77 K. Gd-Ba-Cu-O shows the clear secondary peak effect on the J_c-B curve so that the pinning property was different from Y-Ba-Cu-O for which J_c monotonically decreases with field. The flux motion was enhanced in Y-Ba-Cu-O with increasing static bias field, while that was suppressed in Gd-Ba-Cu-O, reflecting the secondary peak effect.
