Abstract
A simple model is proposed to analyze the relationship between susceptibility and composition in superconducting composites. The model is based on a random distribution of superconducting and nonsuperconducting phases and on the occurrence of shielding when a nonsuperconducting area is encapsulated by superconducting material. A three-dimensional simulation based on percolation theory is in agreement with our experimental data on a series of MgO-superconductor composites. A predicted percolation effect was observed and a maximum in shielding efficiency was determined.
