Large anomalous Nernst effect in a skyrmion crystal. [PDF]

Sci Rep, 2016
AbstractThermoelectric properties of a model skyrmion crystal were theoretically investigated and it was found that its large anomalous Hall conductivity, corresponding to large Chern numbers induced by its peculiar spin structure leads to a large transverse thermoelectric voltage through the anomalous Nernst effect.
