Fig. 4: Field induced anomalous Nernst effect.
a, b Field dependence of Sxy and αxy up to 14 T, with temperature varying from 100 to 400 K. c Comparison of temperature dependence of \({\sigma }_{xy}^{FA}\) and \({\alpha }_{xy}^{FA}\) at 14 T. d Temperature dependence of the Nernst coefficient (υ = Sxy/H) divided by temperature. Measured Nernst signal (the black squares) with the largest value of 6.85 10−4 μVK−2 T−1, becomes two orders of magnitude larger than the estimated ordinary Nernst signal (the red circles) 3.45 10−6μVK−2T−1 estimated by 283μ/EF, here μ and EF are carrier mobility and Fermi energy. e Temperature dependence of the ratio of off-diagonal field induced anomalous Hall and Nernst conductivity (\({\alpha }_{xy}^{FA}/{\sigma }_{xy}^{FA}\)).
