  Thermoelectric 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. This implies the possibility of finding good thermoelectric materials
among Skyrmion systems, and thus motivates our quests for them by means of the
first-principles calculations as were employed here.
