LAB

Ultrafast spin dynamics laboratory
We are currently researching on spintronics and magnetism. In condensed matter physics, one of the most important physical property is spin, which is directly connected to magnetism. We are trying to observe and interpretate the spin dynamics in the magnetic materials, and apply it to the development of spintronic memory or logic devices.
