由跳跃噪声过程驱动的Landau-Lifshitz方程被应用于在很宽的温度范围内的热磁化开关的研究。它表明，在非常低的温度下，磁化翻转偏离热激活理论的预测，并表现出一些功能，传统上归因于磁化的“宏观隧穿”现象。
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.
