  $\tau$-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
$\tau$-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$\pm$0.24) $\mu$V/K at 300 K is comparable to other perpendicular
magnetic anisotropy thin films. Therefore $\tau$-MnAl is a promising candidate
for spin-caloritronic research.
