Research Abstract |
The aims of this study are to establish the quantum mechanical basis for "spinmotive force," a new mechanism of generating an electric voltage by domain wall dynamics, and to propose new concepts in magnetic devices based on this effect. We developed numerical algorisms for calculating the spinmotive force in arbitrary magnetic nanostructures and clarified the relationship between magnetization dynamics and induced spinmotive force. We analyzed spinmotive forces induced by a gyrating magnetic vortex, domain wall motion in a nonuniform nanowire, and ferromagnetic resonance in an asymmetric magnetic thin film. We also proposed a new concept of a magnetic read-head based on the spinmotive force.
