| Abstract(in English) | This paper provides a review of our previous works on microwave assisted magnetization switching from the both sides, analytical study and experiments using perpendicular magnetic nanodots. Analytical model under the basis of macrospin model is derived from the steady-state solution of LLG equation. This model gives the switching behavior which corresponds to the Stoner-Wohlfarth model adopted in the rotating frame. The experiments using the nanodots of Co/Pt multilayer clearly demonstrate that the switching behavior almost follows the analytical model prediction when the dot diameter is 50 nm. On the other hand, for the dot diameter range larger than 100 nm, the microwave assistance effect becomes significantly enhanced due to the excitation of non-uniform precessional motion inside the dot. |
