| Abstract: | In the present letter, the effect of Mn substitution on structure and magnetic properties of YFe12-xMnx compounds has been investigated． All the YFe12-xMnx compounds with 2．0≤x≤5．0 crystallize in the ThMn12 type of structure．The lattice constants and the unit-cell volume increase monotonously with increasing Mn concentration． The Curie temperature and the molecular saturation moments of YFe12-xMnx compounds decreases monotonically with increasing Mn content． |
