The interpretation of the crystal field groundstate of Dy3+ in Pd

A recent interpretation of the crystal field ground state of Dy³⁺ in Pd is discussed in terms of a model where isotropic conduction electron/ion exchange is included. The new results suggest the ratio of fourth and sixth order crystal field parameters to be 292±4. The magnitude of the crystal field parameters cannot be determined. A resonance originating possibly from Dy ions in non-cubic sites is identified.
