Abstract :
The new ternary compound UFe5Ga7 was prepared by an argon arc-melting followed by annealing. This intermetallic compound belongs to the series UFexGa12−x and crystallizes in a structure related with the ThMn12-type, with a = 8.6309 Å and c = 5.0524 Å. EDS elemental analysis yielded the phase composition UFe4.9(2)Ga6.8(1), which is very close to the nominal composition. Dc magnetization measurements revealed ferromagnetic type of magnetic ordering in UFe5Ga7. The Curie temperature of ∼439 K was estimated by the temperature dependence of magnetization at a low magnetic field of 0.1 T.
