Machine-learning-identified two-dimensional van der Waals multiferroics for four-state nonvolatile memory
By combining machine learning screening with first-principles calculations, this study identifies the AuCrPS monolayer as a promising 2D van der Waals multiferroic candidate that enables non-destructive four-state nonvolatile memory through the intrinsic coupling of its ferroelectric polarization and ferromagnetic order via the bulk photovoltaic effect.
