Abstract

The adiabatic Ettingshausen-Nernst coefficient, Q a , and the Righi-Leduc coefficient, R a , have been measured on Alumel and Nickel. The results show that Q a of Alumel increases with temperature and has a precipitous drop near its ferromagnetic-paramagnetic transition temperature ( T c =425.6 K). The experimental Q a relates well with temperature measurements errors experienced using Chromel-P vs Alumel thermocouples in crossed thermal and magnetic fields.
