Jump-noise process-driven magnetization dynamics and random switching of magnetization

2012 
The Landau-Lifshitz equation driven by a jump-noise process is applied to the study of thermal magnetization switching for a very wide range of temperatures. It is demonstrated that at very low temperatures, magnetization switching deviates from the prediction of thermal activation theory and exhibits some features that have been traditionally attributed to the phenomena of “macroscopic tunneling” of magnetization.
