Characterization of monofilamentary and multifilamentary 2223-BSCCO tapes by magnetic loss measurements

The results of measurements of hysteresis loops and related power losses in monofilamentary and multifilamentary 2223-BCCO tapes are presented and discussed in this paper. It is shown that magnetic properties considerably depend on technological processes and differ significantly between mono- and multifilamentary specimens. In particular, the variation of magnetic quantities, e.g. coercive field and residual magnetization, with applied outer magnetic field, as well as the comparison with critical current measurements, support the Bean model and, moreover, help to deduce the effective cross section of the superconductor.
