Abstract
The compounds RFe12−xRex (R Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, Lu, Y, Th, U) were synthesized at the nominal composition x = 2 by arc melting from the elements followed by annealing. The poly crystalline samples were examined by X-ray powder diffraction and magnetization measurements. They all crystallize with a partially substituted tetragonal ThMn12-type structure and are magnetically ordered with Curie temperatures in the range Tc = 340(U)-475(Sm) K and magnetic moments at 4.2 K in the range 8.0(Dy)–21.4(Nd) μB per formula unit. Atomic coordinates are given for two members with refined compositions, PrFe10.5Re1.5 and GdFe10.6Re1.4.
