Abstract
A magnetically hard compound having the approximate formula SmFe.sub.10 V.sub.2 formed by rapidly quenching a molten mixture of the precursors either with or without subsequent annealing exhibits an intrinsic room temperature coercivity of at least 5 kOe. A mixture of samarium, iron and vanadium is melted and then rapidly quenched by metal spinning to form a fine grained structure with magnetic anisotropy as quenched. Alternatively, the molten material is over-quenched and then annealed to optimize the magnetic properties of the alloy.
