    Abstract
    We compare the results of measurements of the magnetic susceptibility χ(T), the linear coefficient of specific heat γ(T)=C(T)/T, and 4f occupation number nf(T) for the intermediate-valence compounds YbXCu4(X=Ag, Cd, In, Mg, Tl, Zn) to the predictions of the Anderson impurity model, calculated in the noncrossing approximation (NCA). The crossover from the low temperature Fermi-liquid state to the high-temperature local-moment state is substantially slower in the compounds than predicted by the NCA; this corresponds to the “protracted screening” recently predicted for the Anderson lattice. We present results for the dynamic susceptibility, measured through neutron-scattering experiments, to show that the deviations between theory and experiment are not due to crystal-field effects, and we present x-ray-absorption fine-structure results that show the local crystal structure around the X atoms is well ordered, so that the deviations probably do not arise from Kondo disorder. The deviations may correlate with the background conduction electron density, as predicted for protracted screening. © 2001 The American Physical Society.

    The export option will allow you to export the current search results of the entered query to a file. Different formats are available for download. To export the items, click on the button corresponding with the preferred download format.

    By default, clicking on the export buttons will result in a download of the allowed maximum amount of items.

    To select a subset of the search results, click "Selective Export" button and make a selection of the items you want to export. The amount of items that can be exported at once is similarly restricted as the full export.

    After making a selection, click one of the export format buttons. The amount of items that will be exported is indicated in the bubble next to export format.
