Sign-reversed anomalous Nernst effect in the ferromagnetic Weyl-semimetal Fe${}_{3-x}$GeTe${}_2$: the role of Fe vacancies

Haiyang Yang, Qi Wang, Junwu Huang +7

Anomalous Nernst effect, as a thermal partner of anomalous Hall effect, is particularly sensitive to the Berry curvature anomaly near the Fermi level, and has been used to probe th…
