Abstract

The geometry of the Brillouin zone of antiferromagnetic NiO (Cc2/c) is studied. The corepresentations of the magnetic little group are deduced for the points and lines of symmetry. The magnon symmetries are investigated and the selection ruies for two magnon electric dipole and magnetic dipole absorption are deduced.
