Query: Interface-induced anomalous Nernst effect in Fe3O4/Pt-based
  heterostructures   We have studied the anomalous Nernst effect (ANE) in [Fe3O4/Pt]-based
heterostructures, by measuring the ANE-induced electric field with a magnetic
field applied normal to the sample surface, in the perpendicular magnetized
configuration, where only the ANE is expected. An ANE voltage is observed for
[Fe3O4/Pt]n multilayers, and we further investigated its origin by performing
measurements in [Fe3O4/Pt/Fe3O4] trilayers as a function of the Pt thickness.
Our results suggest the presence of an interface-induced ANE. Despite of this
ANE, the spin Seebeck effect is the dominant mechanism for the transverse
thermoelectric voltage in the in-plane magnetized configuration, accounting for
about 70 % of the measured voltage in the multilayers.
