โฆ Synopsis
The heat conductivity has been determined for lead, copper and tungsten. For lead an increase of the heat resistance is found at very low temperatures. This resistance is higher in the supraconductive state than in the state in which supraconductivity has been disturbed by means of a magnetic field. This is in complete agreement with the results for other pure supraconductive metals. The so called ideal resistance of copper is still falling at the lowest temperature at which the determinations have been carried out. It is proportional to T2.4. The ideal resistance of tungsten approaches a minimum value.
