The spin-Seebeck effect (SSE), the spin-voltage generation as a result of a temperature gradient, has recently been observed in ferrimagnetic insulator LaY2Fe5O12 films by means of the inverse spin-Hall effect in Pt films. Here we investigate the SSE using LaY2Fe5O12/SiO2(Cu)/Pt systems, where the LaY2Fe5O12 and Pt layers are separated by SiO2 (Cu) thin-film barriers. The experimental results show that the SSE signal disappears in the LaY2Fe5O12/SiO2/Pt system, but the finite signal appears in…

Observation of the spin Seebeck effect

The spin Seebeck effect allows us to pass a pure spin current, a flow of electron spins without electric currents, over a long distance, and is directly applicable to the production of spin-voltage generators, which are crucial for driving spintronic devices.

Transmission of electrical signals by spin-wave interconversion in a magnetic insulator

It is shown that a spin wave in an insulator can be generated and detected using spin-Hall effects, which enable the direct conversion of an electric signal into aspin wave, and its subsequent transmission through (and recovery from) an insulators over macroscopic distances.
