Abstract
Bulk melt textured YBCO samples in the shape of disks were developed f or use as trapped field magnets. The trapped field in single grains wi th 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 mag netic field. This is interpreted in the framework of a model of magnet ic stress induced damage.
