Abstract

A Sm-poor mixture of Fe-substituted Sm₂Co₁₇, having the nominal stoichiometry of Sm_0.080Co_0.645Fe_0.276, was ball-milled to explore the possibility of enhancing its remanence through direct microstructural refinement. With milling, the Sm₂(Co_0.7Fe_0.3)₁₇ compound disassociates to a body-centered-cubic supersaturated SmCoFe solid solution and a residual SmCoFe amorphous phase. Correspondingly, the coercive field values first increase, peaking at 0.83 kOe after 180 min of milling, then decrease with continued milling to
