Abstract

We have observed unconventional asymmetric field dependence of the nonlocal spin signal under a high dc bias current injection. From the systematic studies on the bias current and the field-direction dependencies of the nonlocal signals, the origin of the asymmetry is understood as the anomalous Nernst-Ettingshausen effect driven by the bias current. The bias current dependencies of the spin accumulation signal and the background resistance are also well explained by the thermal effects induced by the bias current.
