Magnetoelectric coupling is of great interest recently to both understand the fundamental physics and device applications. Materials with strong magnetoelectric coupling, high Curie temperature, and large electric polarization are still rare. We suggest a heterostructure that combines the known memory effect of the switchable ferroelectric In2Se3 [Adv. Funct. Mater. 2019, 29, 1808606] with a van der Waals bonded two-dimensional (2D) metal-organic framework (MOF) film. The magnetic ground state of this MOF can be changed from an antiferromagnetic state to a ferromagnetic through hole-doping. We use first-principles calculations to show that in such a heterostructure, adequate doping differences to cause this phase transition are expected from the changes in the interfacial charge transfer between the MOF and In2Se3 when the polarization direction of the In2Se3 is reversed. This and similar 2D heterostructures may, therefore, provide both a fascinating material platform for understanding the fundamental physics of magnetoelectric coupling and a strategy for designing spin-current-based nonvolatile memory structures.
