Abstract

Multiferroics are rare crystals of simultaneous and coupled ferroic orders, allowing disparate external stimuli to induce abrupt transformations in their structures and properties. Creating multiferroicity in two-dimensional (2D) van der Waals (vdW) platforms would invite strong quantum confinement, enhanced quasiparticle excitation, and wide property tunability to interplay, potentially engendering emergent quantum matters and phenomena. Here, we construct vdW heterostructures of Fe3GaTe2/CuInP2S6 to integrate ferromagnetic and ferroelectric orders. Remarkably, we observe the strong inter-ferroic coupling at room temperature, by demonstrating the ferroelectrically reconfigurable magnetic anisotropy of 2D Fe3GaTe2. The inter-ferroic magnetoelectricity exhibits an inversed dependence on the Fe3GaTe2 thickness, revealing the interfacial nature of heterostructure multiferroicity. Our discovery of all-vdW heterostructure multiferroicity opens the door to the artificial assembly of vdW layers for designer 2D multiferroics.
