Journal article
##### Published in
Phase Transitions ; 75 (2002), 1/2. - pp. 67-75
##### Abstract
Magnetization reversal in Co nanostructures is simulated over a wide range of time-scales, from fast switching processes on a ps time-scale to thermally activated reversal on a μs time-scale. Langevin dynamics is used as well as time quantified Monte Carlo methods for the simulation of a classical spin system modeling elongated Co nano-particles. We study the behavior of the magnetization during the reversal, the energy barriers which are relevant for the thermally activated long-time behavior and the corresponding characteristic times.
