Projective Dynamics Analysis of Magnetization Reversal
arXiv:cond-mat/0306168 · doi:10.1016/j.physb.2003.08.093
Abstract
The computational Projective Dynamics method is used to analyze simulations of magnetization reversal in nanoscale magnetic pillars. It is shown that this method can be used to determine the magnetizations corresponding to the metastable minimum and saddle point in the free energy, and the free-energy barrier associated with those points. For the nanopillars studied here, entropy is found to provide a significant contribution to the free-energy barrier which determines the reversal time scale.
