All-electric spintronics: Never say never!

An INAC lab is now one of world’s select few capable of producing a spin current using neither a magnetic field nor ferromagnetic materials. Their secret? A lateral 50 nm platinum nanowire device in which the injector and detector are connected by a central channel. The system measures just 200 nm x 100 nm, and a 100 microampere current generates a spin current of around 1 microvolt. The next step will be to increase the conversion yield to 20% to meet market demands. The INAC lab, which is working in association with Albert Fert’s CNRS lab, has now turned its focus to using two-material combinations and doped materials to achieve better yields.
