alloys, the structural and magnetic states of which are formed at different aging temperatures and cooling rates, are studied. A high coercive force and adequate squareness of the magnetic hysteresis loop of the alloy powders under study are observed at grain and subgrain sizes of the 2 : 17 phase of 10–20 μm. It is shown that the anisotropic powders of the Sm
