Exact Activation Energy of Magnetic Single Domain Particles
arXiv:0705.3761 · doi:10.1016/j.jmmm.2004.05.012
Abstract
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.
