Abstract

We report an enhancement of the anomalous Nernst effect (ANE) in Ni/Pt (001) epitaxial superlattices. The transport and magneto-thermoelectric properties were investigated for the Ni/Pt superlattices with various Ni layer thicknesses (t). The anomalous Nernst coefficient was increased up to more than 1 µV K^-1 for 2.0 nm ≤ t ≤ 4.0 nm, which was the remarkable enhancement compared to the bulk Ni. It has been found that the large transverse Peltier coefficient (axy), reaching axy = 4.8 A K^-1 m^-1 for t = 4.0 nm, plays a prime role for the enhanced ANE of the Ni/Pt (001) superlattices.
