| Annotation |
The results of the numerical study of both circularly polarized magnetic field and thermal fluctuation influence on a uniaxial ferromagnetic nanoparticle are represented in the article. The model of such a system is based on the stochastic Landau-Lifshitz equation. The investigations targeted on the derivation of the optimal switching para-meters for nanoparticle magnetic moment that has two equilibrium states caused by uniaxial anisotropy. |
