Abstract

We measured transverse magneto-thermoelectric voltage on devices made of a Permalloy (Py) line and a transverse electrode made of platinum (Pt), copper (Cu) or bismuth (Bi). We show that the angular dependence of the voltage is the same for Pt and Cu but different with a Bi electrode. We interpret the angular dependence with Pt and Cu electrode as anomalous and planar Nernst and Righi-Leduc effect on Py. The results obtained with a Bi electrode can be explained as the Nernst effect of the electrode itself which overwhelms the signal coming from the Py.
