Description

The microwave absorption spectrum of the high-T/sub c/ granular superconductor YBa2Cu3O/sub 7-//sub δ/ measured in a weak magnetic field with small modulation exhibits reproducible oscillations as a function of external field. We have modeled the high-T/sub c/ ceramics as a network of superconducting wires weakly coupled at randomly placed nodes. Quantum network simulations of the behavior of this system in a magnetic field reveal strong similarities between the computed magnetoconductance, magnetization, and susceptibility and the experimentally observed microwave absorption spectrum
