Exchange frequency resonance consider a Ferrimagnet with two sub-lattices A and B of magnetizations M A ,
Question:
Exchange frequency resonance consider a Ferrimagnet with two sub-lattices A and B of magnetizations MA, and MB, where MB, is opposite to MA when the spin system is at rest. The gyro magnetic ratios are γA, γB, and the molecular fields are BA = – λMB; BB = – λMA. Show that there is a resonance at w20 = λ2 (γA|MB| - γB|MA|2 this is called the exchange frequency resonance.
