Abstract
The simple rock salt structure of the rare-earth monopnictides and monochalcogenides makes them particularly amenable to experimental study and analysis in terms of crystalline electric fields. The early neutron diffraction work performed on these compounds1,2,3 represents, even today, almost the only systematic study of the crystalline electric field in a rare-earth/metal series. Interestingly, it was found that a “simple point charge” model could be used to explain the quantitative magnitude of the crystal field parameters if one allowed two electronic charges to be relocated from the rare-earth to pnictide or chalcogenide site. This transfer of charge has some qualitative support based upon electronegativity arguments.
