Description
Due to the absence of a seizable magnetization in antiferromagnetic spintronics their direct control is difficult and alternative means as, e.g., coupling to a ferromagnet via exchange bias [1], are needed. Antiferromagnetic Co:ZnO was presented as a model system in which uncompensated spins lead to a vertical exchange bias like shift [2] connected to the Co-doping level [3]. We studied temperature and cooling field effects on this vertical shift at different doping levels.
