Observation of anisotropic magneto-Peltier effect
For the first time in the world, NIMS and Tohoku University jointly observed an anisotropic magneto-Peltier effect--a thermoelectric conversion phenomenon in which simple redirection of a charge current in a magnetic material induces heating and cooling. Thermoelectric heating and cooling a ... more
Diamond-based circuits can take the heat for advanced applications
When power generators like windmills and solar panels transfer electricity to homes, businesses and the power grid, they lose almost 10 percent of the generated power. To address this problem, scientists are researching new diamond semiconductor circuits to make power conversion systems mor ... more
Spin-current generation gets mid-IR boost with plasmonic metamaterial
Over the last few years, researchers have demonstrated that light can serve as a spin-current generator, creating currents of angular momentum, in optical nanostructures known as plasmonic absorbers, opening up a new branch of spintronics called opto-spintronics.
Recently, researchers have ... more
