Skyrmion stability in nanocontact spin-transfer oscillators
Source abstract
Abstract
We investigate the conditions for nanocontact spin-transfer oscillators (NC-STOs) that allow for stabilization of a skyrmion. Emphasis is made on the breathing mode, which can be regarded as a source of microwave generation. Micromagnetic simulations of NC-STOs with varying parameters have been performed, with the resulting magnetization plotted in the form of phase diagrams. It is found that control of spin wave mode in conventional STOs can be applied to skyrmion-based STOs.
