The Thermal Conductivity of Metals at Low Temperatures II: The Transition Elements

The thermal conductivity in the range 2-40°K has been measured for Ti, Mn, Fe, Ni, Zr, Cb, Mo, Rh, Pd, Ta, W, Ir, Pt, U, and for a Pb single crystal. As a rule, the metals of group 8 have a much higher conductivity than have the metals of the earlier groups. The values of α and β in the equation for the thermal resistance R =α T 2 +β/ T have been calculated for each specimen. The experiments on Cb indicate that the normal state was not reached in a field of 3300 gauss at temperatures below 5°K.
