Abstract
The crystal-field levels in Sc-Er, Lu-Er, and Y-Dy have been studied by neutron spectroscopy. The spectra for Sc-Er and Lu-Er are similar to earlier published spectra for Y-Er and in agreement with the level schemes deduced from bulk magnetization measurements. Disagreements between the two types of measurement for Y-Dy suggest a correction for magnetic ordering in the analysis of the magnetization data. The reanalyzed magnetization results are fully consistent with the neutron results.
