Abstract:
In this paper, we test the performance and validity of a semi-implicit time-integration scheme, originally applied in quantum dynamics, for use in micromagnetics. The attempt frequency and energy barriers are calculated for Co nanoparticles. Moreover, a fit of the relaxation time to the Arrhenius-Neel law is presented. The semi-implicit time-integration method is very robust and allows time steps up to 3 ps at a temperature of 50 K.
