The 183th Topical Symposium of the Magnetic Society of Japan / The 39th Topical Symposium on Spin-electronics

Dynamics and Relaxation of Magnetization

The magnetization reversal is the most important technology for the developments of the spintronics technology. In order to control the reversal, it is indispensable to understand the dynamics and relaxation of the magnetization. Such researches have overlap with the leading-edge spin-current phenomena, such as spin-torque magnetization reversal, spin-Hall effect, Hanle effect and so on. The dynamics and relaxation are the common issue in the spintronics studies. In this symposium, we are inviting speakers studying on the frontline of research on spin dynamics and relaxation. We hope to generate exciting and stimulating discussion among those interested in this field.
