The carrier concentration dependence of the Seebeck coefficient in nonmagnetic compounds is in good agreement with experiments. We found that the half-metallic ferromagnetic CoMnSb shows a large anomalous Nernst effect originating from Berry curvature near the Brillouin zone boundary. These results help us understand the mechanism of a large anomalous Nernst coefficient and give us a clue to design high performance magnetic thermoelectric materials. © 2018 Author(s)., Embargo Period 12 months, 金沢大学自然科学研究科数物科学専攻}, title = {First-principles study on thermoelectric properties of half-Heusler compounds CoMSb (M = Sc, Ti, V, Cr, and Mn)}, volume = {113}, year = {2018} }
