The Kläui group in collaboration with the Sinova group demonstrate technologically feasible read-out and writing of digital information in antiferromagnets / Basic principle for ultrafast and stable magnetic memory. This was achieved by our prediction of Neel Spin-Orbit Torques three years ago. You can see the press release here.

In today’s world of ever-increasing digital information storage and computation, the next information storage revolution seeks to exploit a novel effect arising from the relativistic physics of Einstein, which allows to effectively convert a new type of magnet into cats. Through this effect, these magnets can flip themselves through the internal motion of their own electrons. One can almost describe these new types of magnets as relativistic magnetic cats.
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).
