Abstract:Measurements have been made of the electronic thermal conductivity of quench-condensed films of lead-manganese and indium-manganese alloys. The results are compared with calculations based on Shiba's theory of superconductors containing magnetic impurities. For Pb-Mn, the value of £ (the normalized position in the energy gap of the excited state assoociated with a single impurity) which was used earlier to explain tunneling measurements, is 0.55; this value is consistent with our data. For In-Mn, the value £ = 0.85 gives excellent agreement with our data. For In-Cr, o the results for one sample are consistent with the value £ = 0.70, but o the data for the other sample fall outside the range allowed by Shiba's theory for any Eo.
