Proximity‐Mediated Multi‐Ferroelectric Coupling in Highly Strained EuO‐Graphene Heterostructures
Advanced Materials, EarlyView.Magneto‐ferroelectric effects in van der Waals EuO/graphene heterostructures emerge via a topotactic method, inducing high compressive strain. This strain stabilizes a ferroelectric state up to room temperature, coexisting with the magnetic proximity effect in graphene.
