Magnetization curves of nanoparticle with single-ion uniaxial anisotropy

The calculations of the magnetization of superparamagnetic nanoparticles were carried out in a model of isotropic intraparticle exchange interaction as well as in a model with isotropic exchange interaction and single-ion anisotropy. These models take into account thermal excitations of atomic magne...

Summary:The calculations of the magnetization of superparamagnetic nanoparticles were carried out in a model of isotropic intraparticle exchange interaction as well as in a model with isotropic exchange interaction and single-ion anisotropy. These models take into account thermal excitations of atomic magnetic moments, of which the total magnetic moment of nanoparticle consists.
