Abstract
The relationship between domain wall motion and magnetization rotation is investigated. A wall motion mechanism previously proposed by the author is examined. The model gives the novel concept that the energy difference between transition state (magnetization curling) and final state (after wall motion) accelerates the wall motion. The magnetic moments in the region coupled with 90° walls rotate more slowly than those moments in the non-coupled region, hence the magnetic flux change is confined to a narrower portion of central domains at higher frequencies.
