Abstract

The compositional dependence of the Curie temperature of the Tb ₂ Fe _17-x Ga _x solid solutions shows a primary maximum for x equal to three and a secondary maximum for x equal to eight. The Mössbauer spectra and powder neutron diffraction patterns of Tb ₂ Fe ₉ Ga ₈ indicate that gallium avoids the 9d site, completely fills the 6c site, and occupies preferentially the 18f site over the 18h site. This gallium preferential substitution leads to a nearly ordered two-dimensional antiferromagnetic arrangement of the terbium and iron magnetic moments, an increase in Curie temperature, and a surprisingly sharp Mössbauer spectrum.
