Model for a collimated spin-wave beam generated by a single-layer spin torque nanocontact
Model for a collimated spin-wave beam generated by a single-layer spin torque nanocontact
A model of spin torque induced magnetization dynamics based upon semi-classical spin diffusion theory for a single layer nanocontact is presented. The model incorporates effects due to the current induced Oersted field and predicts the generation of a variety of spatially dependent, coherent, precessional magnetic wave structures. Directionally controllable collimated …
