The magnetic properties and the changes in the domain structure of alloy Sm(Co, Fe, Cu, Zr)7.5 are studied after different variants of heat treatment, i.e. (1) quenching from 1200°C with cooling in a helium jet; (2) quenching and tempering at 800°C for 16 h, cooling at a rate of 50 K/min to room temperature; and (3) quenching, tempering at 800°C for 16 h, and cooling at a rate of 1.7 K/min. The influence of the heat treatment modes on the coercivity and the domain sizes is determined. The mechanism of variation of these characteristics is analyzed.
