Abstract: The effect of substitution of Mn on the structure and magnetic properties of HoFe12-xMnx (x＝2.0, 3.0, 4.0 and 5.0) compounds was investigated. All the HoFe12-xMnx compounds studied crystallize in ThMn12 type of structure. The lattice constants and unit-cell volume increase monotonously with increasing Mn concentration. The Curie temperature and the moments of the transition-metal sublattice of HoFe12-xMnx compounds decrease monotonously with increasing Mn content. A minimum appears at x＝3.0 in the Mn concentration dependence of the saturation magnetization of HoFe12-xMnx compounds. A compensation point appears in the M(t) curve of the compound with x＝4.0. The mean-field constant nRT of HoFe9Mn3 was calculated.
