Specific heat and magnetic behavior of UTGe compounds

Abstract

The temperature dependence of the magnetic susceptibility, electrical resistivity, and specific heat, as well as the magnetization in fields up to 35 T, of polycrystalline samples of UTGe (T=transition metal) compounds has been studied. The development from nonmagnetic UCoGe and URuGe through the weak ferromagnet URhGe, which displays the highest γ value, to complicated types of the local 5f-moment ordering for T=Pd, Ni, and Pt is in agreement with the expected trends of gradually reduced 5f-d hybridization.
