Abstract
A methodology for investigation of processes of reversal magnetization of nano-heterogeneous high-coercivity magnets of the Sm – Co – Fe – Cu – Zr system at high (600 – 850°C) temperatures by analyzing “frozen” domains at room temperature, in particular, by the method of the Kerr polar magnetooptic effect, is suggested. The methodology is applied to sintered magnets of the Sm – Co – Fe – Cu – Zr system with magnetization coercivity of about 30 kOe at room temperature.
