Abstract
The limiting high-magnetic-field behavior of the electrical and thermal magnetoconductivities of a Pb single crystal withB along [001] have been extracted from data taken in fields of up to 4.3 T in the liquid 4 He temperature range. The electrical conductivity varies asB−2 in the limit of high fields, with the coefficient exhibiting aT5 dependence, the same as is found for the zero-field resistivity. The analogous coefficient for the thermal magnetoconductivity shows aT3 dependence, but there are no zero-field data available for comparison. The lattice conductivity has also been determined and is shown to obey aT2 dependence only below 3 K, with a more rapid dependence between 3 and 4 K.
