Micromagnetic simulations of fast switching in single-domain ferromagnetic particles
In this paper we present the results of numerical simulations concerning the thermal effects in the dynamics and the switching probability of one spin magnetic particle with a thin-film like geometry and in-plane anisotropy.

| Summary: | In this paper we present the results of numerical simulations concerning the thermal effects in the dynamics and the switching probability of one spin magnetic particle with a thin-film like geometry and in-plane anisotropy. The dynamics of magnetization vector is calculated using the LLG equation and Langevin formalism. We have determined the maximum angle of dispersion due to thermal fluctuation as a function of temperature and we calculate the time window when switching has probability 1 and study this as a function of the applied field. |
