Objective was to understand strongly magnetic rare earth-transition metal compounds and alloys, with potential use as hard or semi-hard permanent magnet materials. Efforts were focused on three areas: search for Fe-rich new phases and compounds with high magnetization, anisotropy, and Curie temperature; use of rapid solidification (melt-spinning) to produce fine grain and high coercivity; and relation of hard magnetic properties to microstructure and domain structure. Coercivities of up to 10 to 15 kOe have been produced.
