Suppression of ferromagnetism in URhGe doped with Ru
Abstract
In the correlated metal URhGe ferromagnetic order (TC = 9.5 K) and superconductivity (Ts= 0.25 K) coexist at ambient pressure. Here we report on alloying URhGe by Ru, which enables one to tune the Curie temperature to 0 K. URuGe has a paramagnetic ground state and is isostructural to URhGe. We have prepared a series of polycrystalline URh1-xRuxGe samples over a wide range of x values. Magnetization and electrical resistivity data (T > 2 K) show, after an initial increase, a linear suppression of TC with increasing x. The critical Ru concentration for the suppression of ferromagnetic order is xcr ~ 0.38.
