Abstract

Magnetization measurements of a heavy fermion compound URu₂Si₂ have been performed in the superconducting state. Broad peak structure of the irreversible magnetization was observed around 50 kOe for H∥a. The Ginzburg-Landau parameter obtained from the equilibrium magnetization slightly decreases for H∥c with decreasing temperature, suggesting the presence of the paramagnetic suppression of the superconductivity. However, the suppression is not so large as expected from the H_c2(T) curve. Thermodynamic critical field appears to show unusual temperature dependence.
