Abstract

A new ternary uranium intermetallic compound, U2Fe3Ge, was synthesized and investigated. This compound crystallizes in the MgZn2-type structure (a = 5.1870(3) angstrom and c = 7.8501(5) angstrom, space group P6(3)/mmc), with uranium-uranium distances well below the Hill limit. Magnetization measurements indicate a ferromagnetic-type transition at 55(1) K. Mossbauer studies show that the magnetic ordering is due only to the uranium sub-lattice, pointing to U2Fe3Ge as a new exception to Hill's rule.
