Magnetic properties of actinide elements having the 5f/sup 6/ and 5f/sup 7/ electronic configurations
Magnetic susceptibility measurements have been made on multimicrogram quantities of /sup 243/AmF/sub 3/, /sup 248/CmF/sub 4/, /sup 248/CmO/sub 2/, and /sup 248/CmBaO/sub 3/ samples (nominally the 5f/sup 6/ electronic configuration) and on /sup 248/Cm/sub 2/O/sub 3/, /sup 248/CmF/sub 3/, /sup 249/BkF/sub 4/, and /sup 249/BkO/sub 2/ (nominally the 5f/sup 7/ 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 5f/sup 6/ 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.
