Abstract
A phenomenological approach is used to model the domain structure and reversal of magnetization in Sm(Co,Cu,Fe,Zr)7.5 alloy, along with its transformation after thermal treatment. It is assumed that the reversal of magnetization in these alloys is determined by the strength needed to detach domain walls from the sites to which they are attached. The formation of the domain structure is shown to depend on ratio of the critical strength of the field that detaches the domain walls (i.e., the strength of pinning) and the field of magnetostatic interaction.
