磁性单畴粒子的精确激活能

Exact Activation Energy of Magnetic Single Domain Particles

Daniel Braun

摘要:

给出了单轴各向异性单畴磁性粒子(Stoner-Wohlfahrt模型)激活能随外加磁场变化的精确解析表达式,并研究了激活能在开关边界附近的标度行为。

英文摘要:

I present the exact analytical expression for the activation energy as a function of externally applied magnetic fields for a single--domain magnetic particle with uniaxial anisotropy (Stoner--Wohlfahrt model), and investigate the scaling behavior of the activation energy close to the switching boundary.
