Hi all, Is it possible to ignore the antiferromagnetic order in the symmetry analysis of the phonons? For example, one has to use Mn1 and Mn2 for the manganites when one does a calculation with an antiferromagnetic order. That will (correctly) reduce the point group symmetry from D2h. But many phonon probes are insensitive to magnetism. So it would be nice to do the symmetry analysis of the phonons by ignoring the antiferromagnetic order.
