Gradual Localization of 5f States in Orthorhombic UTX Ferromagnets: Polarized Neutron Diffraction Study of Ru Substituted UCoGe

Popis výsledku v původním jazyce

We report on a microscopic study of the evolution of ferromagnetism in the Ru substituted ferromagnetic superconductor (FM SC) UCoGe crystallizing in the orthorhombic TiNiSi-type structure. For that purpose, two single crystals with composition UCo0.97Ru0.03Ge and UCo0.88Ru0.12Ge have been prepared and characterized by magnetization, AC susceptibility, specific heat and electrical resistivity measurements. Both compounds have been found to order ferromagnetically below T-C = 6.5 and 7.5 K, respectively,which is considerably higher than the T-C = 3 K of the parent compound UCoGe. The higher values of T-C are accompanied by enhanced values of the spontaneous moment mu(spont) = 0.11 mu(B)/f.u. and mu(spont) = 0.21 mu(B)/f.u., respectively in comparison to the tiny spontaneous moment of UCoGe (about 0.07 mu(B)/f.u.). No sign of superconductivity was detected in either compound. The magnetic moments of the samples were investigated on the microscopic scale using polarized neutron diffracti
