Query: Longitudinal Spin Seebeck Effect in Silver Strip on CoFe Film   We report the experimental observation of the spin Seebeck effect (SSE) in
Ag/CoFe noble metal/magnetic metal bilayers with a longitudinal structure.
Thermal voltages jointly generated by the anomalous Nernst effect (ANE) and the
SSE were detected across the Ag/CoFe/Cu strip with a perpendicular thermal
gradient. To effectively separate the SSE and the ANE part of the thermal
voltages, we compared the experimental results between the Ag/CoFe/Cu strip and
Cu/CoFe/Cu strip, where two samples processed with the heating power instead of
the temperature difference through the thin CoFe film. The respective
contributions of the ANE and SSE to thermal voltage were determined, and they
have the ratio of 4:1. The spin current injected through CoFe/Ag interface is
calculated to be 1.76 mA/W.
