摘要：

Single crystal magnetization- and NMR-measurements show that the Cs2NaLnCl6 compounds with the light rare earth Ce and Nd, contrary to that with the heavy rare earth Ho, are tetragonally distorted from cubic symmetry at lower temperatures. Because of this distortion, detailed single crystal magnetization data are required in order to evaluate the Ln crystal-field level scheme. The size of the distortion is such that it splits the ground quadruplet of Nd+3 into doublets nearly two Kelvin apart. © 1979.
