Evolution of ferromagnetic and non-Fermi-liquid states with doping: The case of Ru-doped UCoGe
Original language description
We have investigated the impact of Ru substitution for Co on the behavior of the ferromagnetic superconductor UCoGe by performing x-ray diffraction, magnetization, specific heat, and electrical resistivity measurements on polycrystalline samples of the UCo1-xRuxGe series (0 }= x {= 0.9). The initial Ru substitution up to x approximate to 0.1 leads to a simultaneous sharp increase of the Curie temperature and spontaneous magnetization up to maximum values of T-C = 8.6 K and MS = 0.1 mu(B) per formula unit, respectively, whereas superconductivity vanishes already for x approximate to 0.03. Further increase of the Ru content beyond x approximate to 0.1 leads to a precipitous decrease of both TC and MS towards a ferromagnetic quantum critical point (QCP) at x(cr) = 0.31. Consequently, the T - x magnetic phase diagram consists of a well-developed ferromagnetic dome. We discuss the evolution of ferromagnetism with x on the basis of band structure changes due to varying 5f-ligand hybridizatio
