Abstract
The first evaluations of the crystalline electric field (CEF) parameters A ML <rM> in rare earth compounds were made within the point charge model (PCM)1. If this approach is satisfactory in insulators or ionic compounds, it fails in internetallies because of the presence of the conduction electrons. Indeed, these electrons have a strong anisotropic orbital character around the rare earth as shown by APW band calculations2. The influence of a 5d virtual bound state on the rare-earth impurity was previously investigated in dilute rare-earth noble metal alloys3.The effect of d and f character of the conduction band in rare-earth metals and dilute alloys was studied by Dixon and Dupree4. In addition a possible overlap between hf and conduction electrons wave-functions may generate an exchange electrostatic contribution in addition to the direct one5.
