Microwave absorption by the Josephson network in a low field: Application to ceramic high temperature superconductors

摘要

We discuss the applied magnetic field dependence of the microwave absorption by a three-dimensional array of up to 30 x 30 x 30 Josephson junctions with a random variation of its parameters including the resistivity and the capacity of each junction. The numerical simulation results for the networks show characteristic microwave absorption anomalies observed in the ceramic samples of high temperature superconductor YBa2Cu3O7-x. A brief discussion in analytical terms is also provided. (C) 2003 Elsevier Science B.V. All rights reserved. [References: 11]
