摘要：

The frequency dependence of the surface impedance Z of superconductors has been studied in the frequency range 10 Hz-100 kHz. An essential deviation Z(omega) from the linear law predicted by the usual critical state; model is found. The character of this deviation depends qualitatively on the amplitude of the magnetic field. Results obtained are interpreted in the framework of the modified model where we take into account the contribution of a dissipative term to the screening current. The value of this term is connected with the V-I characteristics of the superconductor, so it is possible to obtain some information about these characteristics by the contactless method.
