Popis:	The magnetic field dependence of the critical current IC(B) and the remanent magnetization of several multifilamentary (BiPb)2Sr2Ca2Cu3Ox tapes were measured. The low field behavior of IC(B) is interpreted by the self-field effect, whereas at higher fields, the field dependence for all tapes was found to be identical except for a constant factor. Although self-field transport critical current densities jC0 differed widely for the tapes, the intergranular critical current densities determined from remanent magnetization were found to be equal. The results indicate that the reduction of jC0 by macroscopic defects is an important factor, whereas locally the filaments are of high quality.
