Magnetic susceptibilities of rare-earth ions in an unusual tetrahedral site
Abstract
Magnetic susceptibilities of the series of compounds Cs2NaR(NO2)6 have been measured for most of the rare earths (R) from Ce to Yb. These materials are cubic, with an unusual Th point symmetry at the rare-earth site. They exhibit not only many similarities but also interesting differences with the related, but octahedrally coordinated, rare-earth elpasolite halides. They are analyzed in terms of a lowest-order crystal-field theory.
