Abstract: | The magnetic susceptibility and Knight shift of the compounds CeCu4 and CeCu5 have been measured over the temperature ranges 80–800 and 140–400 K, respectively. The most important contributions to the magnetic susceptibility are the Curie-Weiss term, expressing the paramagnetism of the localized ?-electrons, and a temperature independent term, which have both been determined. The phenomenological exchange integral Fs? between the 4?-electron spins and conduction electron spins was found to be ?10.43× 10?3 eV for CeCu4 and 3.9 × 10?3 eV for CeCu5. A reversal in the sign of the s?? coupling for CeCu5 is noted. |
