Abstract
The results of electrical resistivity (θ) measurements on the pseudoternary solid solutions, Ce 1-wY wPd 2Ge 2 and Ce 1-vLa vPd 2Ge 2, in the temperature interval 1.4–300K show that the substitution involving Y is less effective in depressing the Néel temperature of Ce sub-lattice than the La substitution in CePd 2Ge 2 (T N ⋍ 5.1K). This observation could be interpreted in terms of the existence of a competition between the two phenomena — magnetism and Kondo effect- in this system. We present evidence to show that the electronic structure changes following iso-valent ionic substitutions should not be ignored in any quantitative understanding of such competing phenomena.
