As Moore's law approaches its physical limits, the development of alternative high-speed, low-energy information technologies based on post-silicon advanced materials has become increasingly imperative. Two-dimensional (2D) ferroic materials, especially involving ferromagnetic, ferroelectric, and their coupling systems, have recently emerged as a frontier research focus in condensed matter physics and materials science. These materials offer unique physical properties and demonstrate tremendous potential for applications in next-generation high-density, low-power information devices. This work provides an overview from ferroic mechanisms to ferroic manipulating strategies and their various applications, demonstrating recently important progress. We emphasized the challenges faced in the scarcity of these intrinsic 2D ferroics, especially for ferromagnetic–ferroelectric materials, point out the potential ways to expand the 2D ferroics source, and offer an artificial intelligence-empowered paradigm roadmap for accelerating their exploration.
