Ab initio DFT calculations predict sizable anomalous Hall conductivity in C-type antiferromagnetic CaCrO3 from Berry curvature hot spots at spin-orbit gapped nodal lines near the Fermi energy.
The transfer between different spin sublattices in the C-AFM configuration makes Cy order invariant un- der the screw operation as it makes Fx order invariant as well
