Magnetic properties of U(Ru1−<i>x</i>Rh<i>x</i>)2Si2 single crystals (0≤<i>x</i>≤1)

Abstract

The temperature dependence of the nonlinear susceptibility of URu2Si2 has been studied in order to understand the properties of the phase transition at 17.5 K. We have also studied the various magnetic phases of U(Ru1−xRhx)2Si2 as a function of x by means of specific heat, susceptibility, and neutron scattering experiments. Special attention has been paid to x=0.3 where two successive phase transitions occur.
