Kondo hole behavior in Ce0.97 La0.03Pd3
Abstract
We present results for the resistivity, the magnetoresistance, and the specific heat of (Formula presented)(Formula presented)(Formula presented) and (Formula presented). The impurity contributions to these measurements follow the predictions of the single-impurity Kondo model for a Kondo temperature (Formula presented)≊65 K, assuming that the impurity behaves as a crystal-field split ((Formula presented)) doublet. Assuming a J=5/2 impurity, the value of (Formula presented) needed to fit these experiments varies from 65 to 125 K. The contribution to the susceptibility may be too small to be explained by the model. These results address whether the nonmagnetic impurity behaves as a Kondo hole. © 1996 The American Physical Society.
