Spin-valve like magnetoresistance and moderate anomalous Hall effect in CoRuMnSn
). Simulations of experimentally observed Ru-Mn antisite disorder reveal pinning of those Mn atoms occupying the Ru sites, aligned antiferromagnetically with other magnetic atoms, thus reducing the net magnetization (3.69μB/f.u.), consistent with experiment. This pinning creates domains with antiferromagnetic/ferromagnetic interfaces, explaining the large asymmetric MR.
