It is found that the high Tc superconductors (HTcSC) are new high-performance material for Nonlinear Magnetics Technology field. Remarkable nonlinear inductances due to the soft magnetic BH hysteresis characteristics are obtained for YBa/sub 2/Cu/sub 3/O/sub 7-chi/ disk-shaped cores at 77{Kappa} which are tightly wound with polyester-coated copper coils. The inductance changes from nearly zero due to the Meissner effect to that of an equivalently core-less coil due to the flux penetration effect with increasing the exciting current or the applied external magnetic field. Values of inductances are almost constant from low frequency to at least 20 MHz. That is, HTcSC is the quick-response nonlinear inductor material.
