    Evolution of magnetism in UCo1-xRuxGe

  • Original language description

    UCoGe is an archetypal 5f-electron ferromagnet (TC ~ 3K) which becomes superconducting at ambient pressure (TSC ~ 0.6 K). The low values of TC and the spontaneous magnetic moment of 0.03 ?B/f.u. indicate nearness of a ferromagnetic instability. We have prepared a series of UCo1MINUS SIGN xRuxGe polycrystalline samples and studied development of the magnetism and superconductivity by measuring the magnetization, specific heat and resistivity as functions of temperature and magnetic field. We have observed that the Ru doping leads to a rapid increase of the TC up to 8.5 K for x = 0.1 and simultaneous suppression of superconductivity. Further doping reduces TC towards a ferromagnetic quantum critical point at x ALMOST EQUAL TO 0.3. The expected quantum criticality is reflected in specific scaling in the temperature dependence of magnetization, specific heat and electrical resistivity. We have also grown an UCo0.88Ru0.12Ge single crystal. It exhibits strong magnetocrystalline anisotropy si
