Abstract
We have measured the thermoelectric power of LaB 6, PrB 6 and NdB 6 in the temperature range 2–20K. PrB 6 and NdB 6 order antiferromagnetically at T N = 6.99 K and 7.74K respectively, whereas LaB 6 is non-magnetic. The thermoelectric power data have a negative maximum near 5.5K in all three hexaborides. This negative peak is thought to be mainly due to phonon drag in LaB 6. In PrB 6 and NdB 6 there is an additional contribution due to magnon drag. It is expected that the high temperature thermoelectric power is mainly due to an electron diffusion term and a contribution due to spin disorder scattering. The thermoelectric power and the resistivity have been compared in the vicinity of T N. A qualitative similarity in the temperature derivatives of these two quantities has been found for PrB 6 and NdB 6 near T N.
