Abstract

Single phase Fe-Sb-Te alloys with NiAs-type structure have been prepared in the composition range from Fe1.173Sb to Fe1.105Te and characterized by X-ray diffraction. Magnetic susceptibility measurements have been taken on these alloys in the temperature range from 77 up to 500 K. The lattice parameters show a linear variation with the alloy composition in the Sb-rich side but an anomalous change for the binary Fe1.105Te. The effective magnetic moments extracted from the susceptibility variations with temperature show a similar anomaly at approximately the same composition. These are discussed in terms of a model of additive magnetic moments of different atomic species.
