Abstract:
The singlet bound state of Ce impurities in the Coqblin-Schrieffer exchange model affected by anisotropy energy is investigated on the basis of the Yosida theory. By the use of the most divergent approximation similar to the one by Ishii for external magnetic fields, an equation is derived to determine the binding energy. Expressions for magnetization and susceptibility are obtained and comparison is made with experimental results.
