Circular and magnetic circular dichroism of some simple antiferromagnetic fluorides

On the discovery of magnon sidebands in insulating antiferromagnets

“…of optical transitions [14], of circular and magnetic circular dichroism [15] and the discovery of biexciton annihilation in this material [16]. And recently, we have been able to identify sublattice splittings in MnF 2 induced by dipolar interactions predicted earlier by one of us (RMW) [17,18].…”
