Sharrock [1][2]推导出硬磁材料矫顽力随时间变化的规律 Hc(t)=H0{1−[kBT/KV×ln(At/0.693)]1/2}(1) 使用 Landau-Lifshitz (LL) 方程的传统微磁学,包含热波动场和温度相关参数,可以考虑热激活;然而,无法达到能量最小值。
Sharrock [1][2] derived a law about the time-dependent coercivity for hard magnetic materials Hc(t)=H0{1−[kBT/KV×ln(At/0.693)]1/2}(1) Conventional micromagnetics using the Landau-Lifshitz (LL) equations, with a thermal fluctuation field and temperature-dependent parameters included, can take the thermal activation into account; however, the energy minimum cannot be achieved.
