Measurements were made of the thermoelectric power at 2 to 20K. The thermoelectric power data exhibited a negative maximum near to 5.5K. This negative peak was thought to be due mainly to phonon drag. It was expected that the high temperature thermoelectric power was due mainly to an electron diffusion term and a contribution due to spin disorder scattering.
