Magnetism

   We have studied magnetic properties of various alloys, thin films and surfaces. In particular, our group has applied our own approaches/codes for the determination of magnetic properties related to the spin-orbit-coupling effect, such as magnetic anisotropy, magneto-optical Kerr effect, magnetic dichroism, and spin Hall effect.
