Effect of Mechanical Stresses on the Coercive Force of the Heterophase Non-Interacting Nanoparticles

Abstract:

The theoretical analysis of the effect of uniaxial stress on the magnetization of the system of noninteracting nanoparticles is done by an example of heterophase particles of maghemite, epitaxially coated with cobalt ferrite. It is shown that stretching leads to a decrease in the coercive force H_c, and compression leads to its growth. The residual saturation magnetization I_rs of nanoparticles does not change. With increasing of interfacial exchange interaction, coercive force varies nonmonotonically.
