摘要
We report on magnetic measurements with a SQUID-magnetometer where the tilt angle between the direction of the c-axis and the magnetic field was varied from 0-degrees (B--> parallel-to c) to 90-degrees (B--> perpendicular-to c). The hysteresis loop was recorded in the range of 0 T to 5.5 T at 77 K. Intense flux creep measurements were performed between 0.03 T and 2 T at 77 K. The increase of the magnetic critical current and the change of flux creep were examined after fast neutron irradiation with different doses.
