An international team of researchers (USA – University of Wisconsin, University of Nebraska, Cornell University, Lawrence Berkeley National Laboratory, Argonne National Laboratory, South Korea, UK, Norway, Ireland) designed a new structure based on antiperovskites to manipulate the flow of spin information without moving the electrons’ charges through the material. Through X-ray diffraction they figured out at what point the structure of the material changed, indicating the emergence of the necessary arrangement of electronic spins. The material develops a magnetic order a little above room temperature. According to the researchers the ability to manipulate the arrangement of electronic spins, as well as their movement through material, has tremendous possibilities for more energy-efficient devices…read more.
