Abstract
Magnetic susceptibility measurements have been made on multimicrogram quantities of , , , and Ba samples (nominally the electronic configuration) and on , , , and (nominally the electronic configuration) in the temperature range 4.2-300 K and in magnetic fields up to 1650 G. The experimentally determined effective magnetic moments and the Curie-Weiss constants for these compounds are presented. The deviation of the moments for the compounds from those expected from classic theory is discussed in terms of low-lying excited states, chemical composition, crystal-field perturbations, and realistic electronic structure.
