Abstract.

In sintered (Nd0.62Dy0.33Sm0.05)16.2(Fe0.77Co0.23)78.1B5.7 alloy, magnetization is governed by nucleation of reverse magnetic domains in the 36-350K range. The contribution of domain wall to magnetization has been found above 150K. The appearance of negative magnetic anisotropy of Sm is accompanied by the suppression of the domain wall contribution to magnetization below T = 120 K. The freezing of domain wall mobility is caused by the competition between the “easy axis” anisotropy of Nd and Dy ions and the “easy plane” anisotropy of Sm ions at low temperatures.
