FIELD: powder metallurgy. SUBSTANCE: process includes smelting an alloy with components being in the ratio (percent by weight) of 24-26 samarium, 16-18 iron, 4.5-3.5 copper and 3.2-3.5 zirconium the balance being cobalt. The resulting alloy is comminuted. Simultaneously added is 0.0015-0.0150 percent by weight amorphous boron powder. The obtained powder is subjected to a magnetic-field compacting followed by sintering and heat treating. EFFECT: simpler process, improved reproducible magnetic properties of product; 70-85% yield of acceptable magnets. 2 tbl
