Microscopic origin of magnetoferroelectricity in monolayer NiBr and NiI
Hui-Shi Yu, Xiao-Sheng Ni, Dao-Xin Yao +1
We investigate the magnetoelectric properties of the monolayer NiX (X = Br, I) through first-principles calculations. Our calculations predict that the NiBr monolayer e…
Room-temperature antiferromagnetic CrSe monolayer with tunable metal-insulator transition in ferroelectric heterostructures
Xiao-Sheng Ni, Yue-Yu Zhang, Dao-Xin Yao +1
Recently, there has been a rapidly growing interest in two-dimensional (2D) transition metal chalcogenide monolayers (MLs) due to their unique magnetic and electronic properties. B…
The discovery of three-dimensional Van Hove singularity
Wenbin Wu, Zeping Shi, Mykhaylo Ozerov +20
Arising from the extreme/saddle point in electronic bands, Van Hove singularity (VHS) manifests divergent density of states (DOS) and induces various new states of matter such as u…
Electrically tunable Gilbert damping in van der Waals heterostructures of two-dimensional ferromagnetic metals and ferroelectrics
Liang Qiu, Zequan Wang, Xiao-Sheng Ni +2
Tuning the Gilbert damping of ferromagnetic (FM) metals via a nonvolatile way is of importance to exploit and design next-generation novel spintronic devices. Through systematical…
In-plane strain tuning multiferroicity in monolayer van der Waals NiI
Xiao-sheng Ni, Dao-Xin Yao, Kun Cao
Multiferroic order with the engineered levels of strain in monolayer NiI is explored based on density functional theory calculations and Monte Carlo simulations. Through the…
Chern insulators and high Curie temperature Dirac half-metal in two-dimensional metal-organic frameworks
Cui-Qun Chen, Xiao-Sheng Ni, Dao-Xin Yao +1
Two-dimensional (2D) magnetic materials with nontrivial topological states have drawn considerable attention recently. Among them, 2D metal-organic frameworks (MOFs) are standing o…
