Spin-charge converters are important devices in spintronics, an electronic which is not only based on the charge of electrons but also on their spin and the spin-related magnetism. Spin-charge converters enable the transformation of electric into magnetic signals and vice versa. Recently, the research group of Professor Jairo Sinova from the Institute of Physics at Johannes Gutenberg University Mainz (JGU) in collaboration with researchers from the UK, the Czech Republic, and Japan has for the first time realized a new efficient spin-charge converter based on the common semiconductor material gallium-arsenide (GaAs).
