When heat ceases to be a mystery, spintronics becomes more real
(PHYSorg.com Physics)

The development of spintronics depends on materials that guarantee control over the flow of magnetically polarized currents. However, it is hard to talk about control when the details of heat transport through the interfaces between materials are unknown. This thermal gap in our material knowledge has just been filled thanks to a Polish-German team of physicists, who now describe in detail the dynamic phenomena occurring at the interface between a ferromagnetic metal and a semiconductor.
