Abstract

The so-called linear reversal mode is demonstrated in spin model simulations of the high anisotropy material L10 FePt. Reversal of the magnetization is found to readily occur in the linear regime despite an energy barrier (KV/kB T) that would conventionally ensure stability on this timescale. The timescale for the reversal is also established with a comparison to the Landau-Lifshitz-Bloch equation showing good agreement.
