Abstract

Dynamic magnetization switching can occur under sub-Stoner-Wohlfarth switching fields, and the switching behavior is well described by the switching phase diagram, showing the regions of non-switching, coherent, and incoherent switching. However, in the incoherent switching region, an alternate switching/non-switching behavior is observed under a strong bias field in the transverse direction, invalidating the usual switching phase diagram. This abnormal switching behavior is explained by a damped oscillation motion of the magnetization, which is restricted by the energy well at a given condition.
