Structural and physical properties of the U(9)Fe(7)Ge(24) uranium germanide
Result description
A new ternary compound, U(9)Fe(7)Ge(24), was synthesized by arc-melting the elements, followed by annealing at 900 degrees C. This compound was characterized by single crystal and powder X-ray diffraction, magnetization, specific heat and electrical transport measurements. It crystallizes in an original tetragonal structure type (space group 14/mmm), with lattice parameters a = 12.3789(2) angstrom and c = 18.2881(3) angstrom. Three uranium, eighth germanium, and three iron crystallographic sites exist in this structure, with the atoms making a stacking of infinite chains along the a and b axis. From their interatomic distances strong interactions between the uranium and germanium atoms can be predicted. The magnetic and specific heat measurements downto 2 K do not show any magnetic transition. The Curie Weiss behaviour with a negative paramagnetic Curie temperature theta p = -94 K and reduced effective magnetic moment of mu(eff) = 2.13 mu(B)/U indicate that the compound is rather far
