Abstract

A polycrystalline sample of composition GaSb + 2% Mn was prepared by melt quenching. Manganese substitutes for gallium positions to form limited solid solution Ga1 − x Mn x Sb, as shown by X-ray powder diffraction and SEM, but most manganese is consumed in the formation of magnetically ordered Mn1.1Sb inclusions having the Curie point T C ≈ 560 K, as shown by magnetic studies.
