The first, YBaMnFeO₅, is a proposed new compound; calculations predict a 2.35 eV band gap and magnetic order up to roughly 420 K (or 490 K after calibration). The authors flag a key synthesis challenge: the ordered Mn/Fe arrangement needed for the predicted spin sorting may not survive high-temperature preparation. The second candidate, KV[Cr(CN)₆], was synthesized in 1999; the authors say its spin sorting was visible in a 2008 study but not identified there as a relevant property. These are computational candidates, not experimentally demonstrated memory materials. http://www.vals.ai/blogs/room-temperature-magnetic-semiconductors
