摘要：

To develop trapped field magnets with YBCO bulks at and below 77 K, a series of trapped field magnets have been developed and tested. With two Phi 26 mm x 10 mm YBCO bulks, a trapped field magnet of 7.09 T at 29.8 K with low creep has been achieved. Cracks occurr when 10 T magnetic field is applied to charge this magnet. With two Phi 16 mm x 10 mm YBCO bulks, a trapped field magnet of 7.02 T at 12.8 K has been achieved. Creep behavior of trapped field magnets at low temperatures are also investigated. When the trapped field is much lower than critical field, almost no creep was observed in our experiments.
