No. You cannot constraint individual atomic moments, but only the total
moment in the unit cell. And in an AFM material this is by definition =
zero.
If you are dealing with a Ferri-magnet, you may use FSM. Again you can
only constrain the total moment, but using partially antiferromagnetic
starting configurations (case.inst: flip the spin for some atoms), you may
have a chance (no guarantee) to stabilize ferrimagnetic solutions with a
certain total moemnt.
