Electric-field switching of two-dimensional van der Waals magnets.
TL;DR: The application of electric fields enables reversible switching of the magnetic order of CrI3 bilayers between antiferromagnetic and ferromagnetic states and achieves a complete and reversible electrical switching between the interlayer AFM and FM states in the vicinity of the inter layer spin-flip transition.
