Abstract

ac losses of sintered and melt-textured YBa2Cu3O7 bars and powder-in-a-tube processed Bi2Sr2Ca2Cu3O10 tapes were measured at 4.2, 65, 70 and 77 K and at 15–180 Hz. In general, the results are well described by the critical state model for the ac losses. However, the losses for the Bi2Sr2Ca2Cu3O10 tapes at 4.2 K exhibited significant contributions from the eddy currents in the Ag sheath.
