One and Two Magnon Light Scattering in Insulating Antiferromagnets and Its Possible Relevance for the Investigation of the Short Range Interatomic Correlations
Although the possibility of light scattering by magnons was considered theoretically as early as 1959 , it was only in 1966 that the first observation of the phenomenon was reported in FeF2 . Since then an intense experimental activity has followed in a variety of antiferromagnetic systems, ranging from rutiles (MnF2, CoF2, NiF2) to perovskites (RbMnF3, KNiF3) and rock salt structures (NiO).
