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

Leonid Afremov, Yury Kirienko

In the dual-phase model of interacting nanoparticles stretching leads to a decrease in both coercive force $H_c$ and saturation remanence $I_{rs}$, and compression - to their growth. Magnetostatic interaction between particles also decreases both $H_c$ and $I_{rs}$. Theoretical analysis was carried out in the framework of the dual-phase system of interacting particles on the example of nanoparticles $\gamma$-$Fe_2O_3$, epitaxially coated with cobalt.
