Processes of reversal magnetization in Sm(Co, Cu, Fe, Zr) 7.4-type alloys are simulated on the basis of the assumption that this process is determined by difficulty of detachment of domain walls from the places of their fixation. The behavior of the material is studied under magnetization after different methods of demagnetization, i.e., cyclic and thermal ones, and by a negative field. The obtained distributions of the fixing fields are used to plot minor loops for actual magnets. The computed and experimental data are compared.
