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 in this study.
对一种模型斯格明子晶体的热电性质进行了理论研究，发现其由特殊自旋结构诱导产生的大陈数所对应的大反常霍尔电导率，通过反常能斯特效应导致产生大的横向热电压。这意味着在斯格明子体系中有可能找到优良的热电材料，从而促使我们通过本研究中所采用的第一性原理计算来探寻这类材料。
