Magnon Excitation

We develop a quantum theory to deal with the coherent magnon excitation in monolayer magnetic nanodots induced by a circularly polarized light. In our theoretical model, the exchange interaction, the magnetic dipole interaction and the light-matter interaction are all taken into account and an effective dynamic equations governing the magnon excitation is derived by a continuum approximation. Our theoretical model shows that the helicity of light and the magnetic dipole interaction govern the magnon excitation and result in the occurrence of various patterns for the spin z-component distribution. We present a scheme to manipulate the single-mode magnon excitation by properly tuning the light frequency.

Recent Project

Work on magnetism, spintronics and multiferroics has generated a great deal of new insight in the field of nanotechnology. According to Professor Tatsuki Oda, who is an expert in this field, one of the most important advancements is the new computational approach to assessing magnetic anisotropy energy (MAE) in antiferromagnets and ferrimagnets in realistic materials. Oda and his team from the Kanazawa University in Japan have taken this unique approach to achieve a world first - offering new tools to help researchers overcome the existing difficulties experienced in measuring antiferromagnetism. In a recent project, Oda's team have been considering the development and application of the density functional approach with spin density magnetic dipole interaction.
