Abstract

Magnetization curves for a polycrystalline specimen of ErRh4B4 are analyzed to estimate the paramagnetic contribution to the Gibbs free energy as well as the differences in free energy between the superconducting and normal states. These results are compared with the theoretical predictions of a suitably constrained model based on Ginzburg-Landau theory for magnetic superconductors.
