Longitudinal Spin Seebeck Effect Free from the Proximity Nernst Effect
Longitudinal Spin Seebeck Effect Free from the Proximity Nernst Effect
This Letter provides evidence for intrinsic longitudinal spin Seebeck effects (LSSEs) that are free from the anomalous Nernst effect (ANE) caused by an extrinsic proximity effect. We report the observation of LSSEs in $\mathrm{Au}/{\mathrm{Y}}_{3}{\mathrm{Fe}}_{5}{\mathrm{O}}_{12}$ (YIG) and Pt/Cu/YIG systems, showing that the LSSE appears even when the mechanism of the proximity …
