Spin Seebeck mechanical force.

ABSTRACT: Electric current has been used to send electricity to far distant places. On the other hand, spin current, a flow of electron spin, can in principle also send angular momentum to distant places. In a magnet, there is a universal spin carrier called a spin wave, a wave-type excitation of magnetization. Since spin waves exhibit a long propagation length, it should be able to send angular momentum that can generate torque and force at a distant place: a new function of magnets. Here we observe mechanical angular momentum transmission and force generation due to spin waves injected into Y₃Fe₅O₁₂ by the spin-Seebeck effect. The spin-wave current, transmitted through a Y₃Fe₅O₁₂ micro cantilever, was found to create a mechanical fo
