Magnetic Studies of Ternary Germanides U3Co4Ge7 and U3Co2Ge7 with Strong Uniaxial Anisotropy

Original language description

U3Co4Ge7 and U3Co2Ge7 have been prepared as single crystals by the solution growth method from tin flux and studied by X-ray diffraction, magnetic, transport, and specific-heat measurements; ab initio electronic-structure calculations have also been performed to study magnetism theoretically. U3Co4Ge7 has a tetragonal structure (I4/mmm), while U(3)Co(2)G(e)7 crystallizes in en orthorhombic structure (Cmmm), which appears to be a distortion of a tetragonal structure. All measurements document ferromagnetism in U3Co4Ge7 below T-C = 21 K with a strong magnetocrystalline anisotropy. The c-axis has a strong ferromagnetic contribution to magnetization and was found to be the easy-magnetization direction. U3Co2Ge7 orders magnetically below 40 K; the magneticstructure is sensitive to the ratio a/c approximate to 1, e. g., the deviation from the tetragonal axis.
