A team of researchers from the University of California, Lawrence Berkeley National Laboratory, the Nuclear Research Center—Negev and the National High Magnetic Field Laboratory has developed a way to isolate antiferromagnet (AFM) heterostructures in the absence of a ferromagnet (FM) to study the coupling that occurs between AFM order parameters and spin-glass parameters. In their paper published in the journal Nature Physics, the group describes an exchange bias set in a spin-glass phase that could arise in a disordered antiferromagnet. Minhyea Lee, with the University of Colorado has published a News & Views piece in the same journal outlining the work done by the team.
