Abstract

Transport critical currents in Ag-sheathed, Bi-based superconducting tapes were measured at various temperatures and in magnetic fields up to 8 T, with the field direction parallel and normal to the tape surfaces. The anisotropy of the critical currents was small in the temperature range below about 25 K but increased with increasing temperature, which might be due to the relatively large difference in critical fields when the magnetic field was applied normal and parallel to the tape surfaces. The angular dependence of the critical current was small at low temperatures but increased with increasing temperature and magnetic field. However, the strong anisotropy peak, which has often been observed in thin films, was not obtained in the present study.
