Multiferroic nitride perovskites with giant polarizations and large magnetic moments
Churen Gui, Jun Chen, Shuai Dong
Multiferroics with coupling between ferroelectricity and magnetism have been pursued for decades. However, their magnetoelectric performances remain limited due to the common trade…
Stacking dependent ferroelectricity and antiferroelectricity in quasi-one-dimensional oxyhalides NbO
Wencong Sun, Ning Ding, Jun Chen +4
Low-dimensional ferroelectricity and polar materials have attracted considerable attentions for their fascinating physics and potential applications. Based on first-principles calc…
Unusual electric polarization behavior in elemental quasi-2D allotropes of selenium
Dan Liu, Lin Han, Ran Wei +4
We investigate tunable electric polarization and electronic structure of quasi-two-dimensional (quasi-2D) allotropes of selenium, which are formed from their constituent one-dimens…
Phase Transitions and Superconductivity in Ternary Hydride LiSiH at High Pressures
Sixuan Wu, Bin Li, Zhi Chen +7
We predicted a new ternary hydride LiSiH at high pressures. A systematic structure search in LiSiH compound reveals novel stable phases with intriguing electronic a…
Magneto-optical Kerr effect and magnetoelasticity in weak ferromagnetic RuF monolayer
Na Wang, Jun Chen, Ning Ding +3
Considerable research interest has been attracted to noncollinear magnetic structures for their intriguing physics and promising applications. In this work, based on relativistic d…
Gadolinium halide monolayers: a fertile family of two-dimensional 4f magnets
Haipeng You, Ning Ding, Jun Chen +2
Two-dimensional (2D) magnets have great potentials for applications in next-generation information devices. Since the recent experimental discovery of intrinsic 2D magnetism in mon…
