摘要: In order to investigate hysteresis losses on Ag-sheathed BSCCO(2223) multifilamentary tapes, we perform loop measurements, with the external magnetic field He perpendicular tape surface, for different sweep rates of and at temperatures T. The experimental results show a rate dependence, equivalent frequency dependence hysteretic losses. consider role thermally activated flux creep in numerically solve diffusion equation B inside superconducting slab. For lower than 2.5 T temperature range investigated, numerical that have logarithmic rate. higher increasing temperature, behaviour is no longer observed frequencies.
