Abstract
Generality of the spontaneous and stimulated magnetization reversal in MnSb clusters embedded in GaMnSb thin films is established. In experiments, the similarity of the thermoactivation and field magnetization reversal processes can be observed as the coincidence of the maximum in the field dependences of magnetic viscosity S(H) with the sample coercivity HC. Analysis of this experimental fact yields the relation between HC and parameters of the model describing the S(H) dependences. The obtained formula is identical to the well-known Kneller law determining the HC(T) dependence of noninteracting superparamagnetic nanoparticles.
