Abstract

Nonstationary processes of microwave absorption in a superconducting ceramic sample of Y-Ba-Cu-O have been studied. A method of direct measurement of microwave absorption by detection of the sample-temperature changes versus an external magnetic field has been designed. A thermodynamical description of the studied phenomena is proposed as a generalization of the model of local temperature T* of the Josephson-junction system in granular superconductors. The results are in good agreement with the predictions of the model of weakly linked superconducting clusters presented by Ebner and Stroud.
