AC susceptibility with superimposed DC magnetic field in a current biased granular high Tc superconductor
We have investigated the effect in AC magnetic susceptibility, κ{script}ac=κ{script}′+jκ{script} ″, of both DC transport current, Jt, and DC magnetic field, Hdc, in polycristalline HTSC. Two regimes are observed: at low DC fields critical state is modified by the current self field; but as Hdc is in...
