直線偏光レーザー照射下の磁性絶縁体接合系で創出されるマグノンスピン流の生成機構を明らかにする。

Using a junction of the ferromagnetic insulators irradiated by linearly polarized laser, we propose a method for the generation of dc and ac spin currents of magnons across the junction interface, and provide an analytical formula for magnon transport induced by the inversion symmetry breaking.
