Theoretical Study on the Microwave Assisted Reversal of Magnetic Moment for Graining


Article Preview

This paper presents the dynamic precession of the moments of the grains based on LL equation, and the impact of the interaction between the grains on the minimum switching field threshold and the speed of the switching process in the microwave field is investigated.As an isolate grain, microwave assisted switching could enhance minimum switching field threshold and switching speed.
