When heat ceases to be a mystery, spintronics becomes more real

(The Henryk Niewodniczanski Institute of Nuclear Physics Polish Academy of Sciences) 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 the Polish-German team of physicists, who for the first time described in detail the dynamic phenomena occurring at the interface between a ferromagnetic metal and a semiconductor.
