Two-dimensional (2D) ferromagnetic and ferroelectric materials attract unprecedented attention due to the spontaneous-symmetry-breaking induced novel properties multifarious potential applications. Here we systematically investigate a large family (148) of 2D MGeX3 (M = metal elements, X O/S/Se/Te) by means high-throughput first-principles calculations, focus on their possible ferroic including...

Two-dimensional (2D) magnets have great potentials for applications in next-generation information devices. Since the recent experimental discovery of intrinsic 2D magnetism monolayer CrI3 and few-layer Cr2Ge2Te6, intense studies been stimulated pursuing more revealing their intriguing physical properties. In comparison to based on 3d electrons, 4f electrons can provide larger magnetic moments ...
