Measurements of Thomson Coefficients for Metals at High Temperatures and of Peltier Coefficients for Solid-Liquid Interfaces of Metals

Apparatus has been devised for measuring and measurements made of Thomson coefficients of metals at high temperatures. It is found that in the range from 400°C to the melting point the approximation $\sigma =\beta T$ is adequate for platinum, palladium, copper, and silver but not for gold, molybdenum, and tungsten.
