Electric and optical response in magnetic system is often characterized in terms of spin-magnetic order parameters, which depend critically on the relativistic spin-orbit coupling. A systematic and unified analysis of such responses can be provided by regarding the latter as a symmetry breaking term in an otherwise spin-group symmetric system.

We use anomalous Hall effect as an example to illustrate how such an approach can provide insight and understanding of a diverse set of phenomena in ferro and antiferro magnetic systems.
