Abstract
ferroelectric monolayer. The weaker interlayer exchange coupling of the CrOBr bilayer makes it easier to be regulated by ferroelectric polarization, enabling reversible nonvolatile electric control of shifts between ferromagnetic and antiferromagnetic ordering. The unique electrically controlled interlayer magnetic coupling for tuning the overall magnetism may be available for the practical application of 2D vdW bilayer magnets in high-sensitivity sensors and high-density data storage.
