摘要：

Bulk melt textured YBCO samples in the shape of disks were developed for use as trapped field magnets. The trapped field in single grains with diameter of 24 mm reached maximum values up to 0.56 T at 77 K and a value of 5.5 T at 30 K, Degradation of the trapped field was observed in samples after the activation process at 20 K in a high applied magnetic field. This is interpreted in the framework of a model of magnetic stress induced damage.
