| contents | In this paper we theoretically describe a distinct class of two-dimensional Néel ordered metallic antiferromagnets on a honeycomb-like lattice in which the two sublattices are connected only by a combination of time-reversal and mirror symmetry operations. As a result of this symmetry, conducting fermions have antiferromagnetic spin-splitting consistent with the symmetry, the mirror-symmetric spin-splitting. It is shown that the anomalous spin Hall effect is expected in such systems. We also consider a system in which there are no symmetries between the sublattices and obtain asymmetric spin-splitting. Such systems are expected to have the anomalous Hall effect. |
