Abstract

Based on the granular model of ceramic superconductors, it is shown that the magnetoresistance associated with dissipation in Josephson junctions is an excellent magnetometer with which to determine the field at the surface of superconducting grains. This result is used to determine the field where vortices penetrate into the grains.
