Layertronics, engineering the digital properties by layer diploma of freedom, has attracted appreciable consideration as a result of its promising purposes in next-generation spintronic applied sciences. Right here, by coupling sliding ferroelectricity with A-type antiferromagnetism, we reveal a mechanism for layer-polarization engineered digital property by the symmetry evaluation based mostly on tight-binding (TB) mannequin. It’s discovered that the inversion symmetry and time-inversion symmetry breaking within the mannequin offers rise to ferroelectricity and layer-polarized anomalous valley Corridor impact. Crucially, this valley polarization is ferroelectrically switchable, enabling non-volatile electrical management of layer-resolved Berry curvature. Utilizing first-principles calculations, this mechanism and phenomena is verified in multiferroic bilayer Janus RuClF. Our findings present a promising platform for 2D bilayer supplies, which maintain nice potential for purposes in nanoelectronic and spintronic units.
