摘要：

Experimental results of measurements of the AC transport current losses on silver sheathed (Bi,Pb)(2)Sr2Ca2Cu3Ox multifilamentary tapes are presented. In the frequency range 33-180 Hz the self-field losses are hysteretic. Transport loss changes due to low DC, applied transverse magnetic fields are also studied. External transverse DC magnetic field causes an increase in the transport losses due to lowering of the critical current I-c of the superconductor. Critical current dependence on the external magnetic field extracted from loss data is compared with that measured directly by standard DC four-probe measurements.
