LXXXI. Heat conductivities of superconductive Sn, In, Tl, Ta, Cb, and Al below 1°K

Abstract The heat conductivities of tin, indium, thallium, columbium, tantalum and aluminium below 1°K have been determined. At the lowest temperatures some of the specimens show a proportionality of the heat conductivity with T3 and it has been suggested that this is heat transport by the crystal lattice only. The bearing of these results on the superconductive heat switch has been discussed.
