Currents of electron spin can travel more than half a micron through germanium at room temperature, according to researchers in Japan and the UK. While physicists already know that germanium is a good conductor of spins at very low temperatures, this is the best measurement yet of its ability to transport spin at room temperature. The results suggest that the semiconductor could be used to create spintronic devices, which make use of the spin magnetic moment of the electron to store and process information….
