Abstract
Susceptibility and resistivity measurements on some alloys of Ho, Dy, Yb and Gd dissolved in Au have been made. The susceptibility results are analysed in terms of the crystal field parameters C4 and C6 which give the best fit to the results have been determined. A low-temperature decrease with decreasing temperature observed in the resistivity of alloys containing the solutes Dy and Ho is explained in terms of the s-f scattering (including inelastic effects) of conduction electrons from the low-lying crystal field-split energy levels. Interaction effects between solute atoms which have been thought by many authors to contribute to the observed properties are found to be rather weak and insignificant compared with the crystal field effects even for the maximum soluble concentrations of rare-earths in gold
