Researchers from Japan's National Institute for Materials Science have developed a wavelength-selective plasmonic metamaterial absorber (PMA) on top of a spintronic device. The researchers say that this design enhances the generation of spin currents from the heat produced in the mid-infrared regime.

The researchers used a mid-infrared plasmonic metamaterials, combined with a spintronics device for the first time. This unique combination enables stronger light absorption and shows the excellent tenability of these metamaterials' resonance wavelengths
