Paramagnetic Effect in High \mbi{T}c Superconductors —A Hint for d-Wave Superconductivity
Abstract
The paramagnetic effect found experimentally in some granular high temperature superconductors is explained by a model of a Josephson network of d-wave superconductors. The unusual microwave absorption characteristics of these systems is also explained in a consistent way. Finally, a new experiment is proposed to give a decisive test for d-wave superconductivity in high Tc superconductors.
