## Description

- description: Van der Waals heterostructures offer great versatility to tailor unique
    interactions at the atomically flat interfaces between dissimilar layered materials
    and induce novel physical phenomena. By bringing monolayer 1T’ WTe2, a two-dimensional
    quantum spin Hall insulator, and few-layer Cr2Ge2Te6, an insulating ferromagnet,
    into close proximity in an heterostructure, we introduce an interfacial exchange
    interaction to transform the former into a ferromagnetic quantum spin Hall insulator,
    manifested by the anomalous Nernst effect, anomalous Hall effect as well as anisotropic
    magnetoresistance effect. Using local electrodes, we identify separate transport
    contributions from the metallic edge and insulating bulk components. When driven
    by an AC current excitation, the second harmonic voltage responses closely resemble
    the anomalous Nernst responses to an AC temperature gradient generated by a nonlocal
    heater, which appear as nonreciprocal signals with respect to the magnetization
    orientation. Our results shed light on the nature of the ferromagnetic quantum
    spin Hall insulator edge states that are qualitatively distinct from the chiral
    or helical edge states in other topological systems.
