We report thermal imaging of the spin Peltier effect; using active thermography technique,
we visualize the temperature modulation induced by spin currents injected into a magnetic insulator from an adjacent metal.

DetailsWe are the leading research team to drive the new paradigmshift of “spin”, a novel property of nature. Our challenge is to innovate the use of spin in ways totally different from conventional spintronics approaches.
Spin is the internal angular momentum of electron. This mysterious rotation of electron has attracted a lot of attentions during the last decade in the context of spintronics, where spin plays the role of information carrier. But, there is more. We have revealed a hidden capability of spin: rectifying random fluctuations to workable energy. This novel capability originates from spin’s inherent property: “violation of time reversal symmetry”. We are opening the new horizon of spin science to innovate the use of spin. This project is supported by Japanese government via ERATO research funding program.
