Effect of mechanical stresses on coercive force and saturation remanence of ensemble of dual-phase interacting nanoparticles

In the dual-phase model of interacting nanoparticles stretching leads to a decrease in both coercive force Hc and saturation remanence Irs , and compression — to their growth. Magnetostatic interaction between particles also decreases both Hc and Irs . Theoretical analysis was carried out in the framework of the dual-phase system of interacting particles on the example of nanoparticles γ-Fe2 O3, epitaxially coated with cobalt.
