## Description

- description: The van der Waals interaction enables thin layers of two-dimensional
    materials to be interfaced in heterostructures with relaxed epitaxy conditions.
    However, the ability to freely stack layers without any strain or structural modification
    is by no means universal. In this work, we utilize the piezoelectricity of α-In2Se3
    to modify the magnetic properties of thin layers of the vdW ferromagnet Fe3GeTe2,
    resulting in increased domain wall density, reductions in the transition temperature
    ranging from 5 to 20 K, and an increase in the magnetic coercivity. Structural
    modifications at the atomic level are corroborated by a decrease in the Tuinstra-Koenig
    ratio, I(D)/I(G) in a graphite/α-In2Se3 heterostructure. Density functional theory
    calculations show that the Fe3GeTe2 layer is compressively strained by 0.4%. The
    incorporation of α-In2Se3 may be a general strategy to electrostatically strain
    interfaces in magnetoelectric vdW heterostructures.
