The research community is intensively searching for new materials, hopefully showing superconductivity under ambient conditions, which would solve many of the most pressing problems of the current era of information technology. For a target-oriented search of such materials, the electron properties of the basic constituents of Hund’s metals need to be understood in detail, and this requirement was lacking so far.
Researchers from the Institute of Physics of the Academy of Sciences of the Czech Republic, in collaboration with researchers from Barcelona, Berkeley, and Halle have demonstrated an experimental spin-based microelectronic device using an antiferromagnetic semiconductor compound Sr2IrO4.
