Abstract

The stability of the intermetallics Gd 3(Fe,T) 29 and the site preferences of the ternary 3d or 4d transition element T were investigated using a series of inter-atomic pair potentials. The calculated results show that either V, Ti, Cr, or Mo atoms can stabilize Gd 3(Fe,T) 29 with monoclinic symmetry. The order of site preference of these stabilizing elements T is 4 i2, 4 i1 and 4 g, where 4 i2 corresponds to the greatest energy decrease. The calculated lattice parameters were found to be in good agreement with experiment. It is surprising that simple pair potentials can describe these extremely anisotropic materials. The calculated results also show that the addition of Cu and Ag does not stabilize the Gd 3(Fe,T) 29 phase.
