Abstract
Anomalous thermal behaviour on EPR linewidths has been observed for Gd impurities diluted in CePd{sub 3}-intermediate valent compound. In this work we show that the exchange interaction between the local magnetic moments and the intermediate valence host ions has an important contribution to the relaxation rates of the local moments. The relaxation is calculated using the Red-field formalism and the ideas contained in the interconfigurational fluctuation model of Hirst. We show that the exchange interaction contribution has an exponential dependence on the excitation energy of the intermediate valent ions. (author). 22 refs, 1 fig.
