Separation of longitudinal spin Seebeck effect from anomalous Nernst effect: Determination of origin of transverse thermoelectric voltage in metal/insulator junctions
Abstract
The longitudinal spin Seebeck effect (LSSE) and the anomalous Nernst effect (ANE) are investigated in various metal/insulator junction systems and a clear separation of the LSSE from the ANE induced by static magnetic proximity is demonstrated. This separation is realized by comparing transverse thermoelectric voltage in in-plane magnetized (IM) and perpendicularly magnetized (PM) configurations, where the LSSE appears only in the IM configuration while the ANE appears both in the IM and PM configurations. We show that, in Pt/Y${}_{3}$Fe${}_{5}$O${}_{12}$ samples, the LSSE voltage in the IM configuration is three orders of magnitude greater than the proximity-ANE contamination estimated from the data in the PM configuration. This quantitative voltage comparison between the IM and PM configurations is corroborated by systematic voltage measurements in Ni${}_{81}$Fe${}_{19}$/Gd${}_{3}$Ga${}_{5}$O${}_{12}$, Pt/Gd${}_{3}$Ga${}_{5}$O${}_{12}$, Au/Y${}_{3}$Fe${}_{5}$O${}_{12}$, and Au/Gd${}_{3}$Ga${}_{5}$O${}_{12}$ samples and by our phenomenological model calculation. The LSSE measurements in high magnetic field regions further confirm that the observed voltage in the Pt/Y${}_{3}$Fe${}_{5}$O${}_{12}$ and Au/Y${}_{3}$Fe${}_{5}$O${}_{12}$ samples is of magnon origin. We apply this voltage comparison method also to a Ni${}_{81}$Fe${}_{19}$/Y${}_{3}$Fe${}_{5}$O${}_{12}$ sample and show that both the LSSE and ANE exist in this sample.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
