Anomalous Nernst effect in perpendicularly magnetised {\tau}-MnAl thin films

Materials Science 2023-07-10 v1

Abstract

τ\tau-MnAl is interesting for spintronic applications as a ferromagnet with perpendicular magnetic anisotropy due to its high uniaxial magnetocrystalline anisotropy. Here we report on the anomalous Nernst effect of sputter deposited τ\tau-MnAl thin films. We demonstrate a robust anomalous Nernst effect at temperatures of 200 K and 300 K with a hysteresis similar to the anomalous Hall effect and the magnetisation of the material. The anomalous Nernst coefficient of (0.6±\pm0.24) μ\muV/K at 300 K is comparable to other perpendicular magnetic anisotropy thin films. Therefore τ\tau-MnAl is a promising candidate for spin-caloritronic research.
