Abstract
In this paper we present the influence of microwave power and temperat ure on magnetically modulated microwave absorption (MMMA) in the granu lar ceramic superconductor YBa2Cu3O6.9 (Y-123 phase). A simple Josephs on junction local-temperature model describing observed changes of MMM A linewidths as a function of microwave power is proposed. The agreeme nt between experimental results and the proposed model proves that in high-temperature superconductors absorption of microwave power occurs mainly in intergrain Josephson junctions of a ceramic sample.
