SPICE Workshop on Ferrons and Magnons: friends or foes? July 7th - 9th, 2026
Kenji Yasuda
Interlayer sliding in van der Waals heterostructures provides a powerful degree of freedom for engineering quantum states of matter. In this talk, I will show how gate-controlled sliding motion between atomically thin layers can be used to reversibly switch both ferroelectricity and magnetism. By designing heterostructures in which the breaking of inversion symmetry is tied to the relative registry of adjacent layers, we realize ferroelectric states whose polarization is governed by interlayer translations. I will also discuss how this sliding motion couples to magnetism in graphene-based systems, enabling gate-induced on-off switching of magnetic order. These results establish interlayer sliding as a versatile control knob for multifunctional 2D devices.
