dc.description.abstractWe investigate the longitudinal spin Seebeck effect in CoFeB/NM bilayers, with Ta, Pd and Ru as non-magnetic NM material. By means of a quantitative approach using an equivalent circuit model, we determine the accurate voltage due inverse spin Hall effect measured in the non-magnetic layer beyond unveiling the role of anomalous Nernst effect and thermoeletric effects provide by metallic ferromagnetic CoFeB layer. From experimental results, we estimate the spin Seebeck coefficient for the bilayers, finding values quite compatible with those for ferromagnetic insulators reported in literature. Moreover, we address the angular dependence of the voltage curves, disclosing the non-magnetic layer affects the effective magnetic anisotropy of the whole bilayer. Hence, our results suggest the effective magnetic anisotropy may be modified to improve the thermoelectric voltage response in ferromagnetic/non-magnetic metal bilayers.
