Abstract: On the basis of a mathematical model of the electrodynamic level of rigor taking into account the exchange and “exchangeless” approximation, the authors have numerically investigated the influence magnetostatic dipolar and exchange interactions in Ni0.7Zn0.3Fe2O4 nanoparticles located in 3D-opal nanocomposite with different number of accountable magnetic particles of spherical geometry in the cell, considering the filling factor of the magnetic component to be a constant. It is shown that the magnetic interactions, both the dipolar and exchange interactions, may be the ways to modify the effective permeability of 3D nanocomposite.
Keywords: magnetic interactions, exchange interaction, dipolar interaction, magnetic nanoparticles, 3D-nanocomposite, opal matrix, effective permeability.
