Chiral magnetism in lithium-decorated monolayer CrTe: Interplay between Dzyaloshinskii-Moriya interaction and higher-order interactions
Weiyi Pan, Changsong Xu, Xueyang Li +4
Chiral magnetic states in two-dimensional (2D) layered noncentrosymmetric magnets, which are promising advanced spintronic materials, are usually attributed to Dzyaloshinskii-Moriy…
Bilayer Stacking Ferrovalley without Breaking Time-Reversal Symmetry
Guoliang Yu, Junyi Ji, Changsong Xu +1
Non-volatile manipulation of valley polarization in solids has long been desired for valleytronics applications but remains challenging. Here, we propose a novel strategy for non-v…
Unconventional Ferroelectricity in Violation with Neumann's Principle
Junyi Ji, Guoliang Yu, Changsong Xu +1
The physical properties of crystals are governed by their symmetry according to Neumann's principle. However, we present a case that contradicts this principle wherein the polariza…
Atomistic Origin of Diverse Charge Density Wave States in CsVSb
Binhua Zhang, Hengxin Tan, Binghai Yan +2
Kagome metals AV3Sb5 (A=K,Rb,or Cs) exhibit intriguing charge density wave (CDW) instabilities, which interplay with superconductivity and band topology. However, despite firm obse…
Competing multiferroic phases in monolayer and few-layer NiI
Nanshu Liu, Cong Wang, Changlin Yan +4
A recent experiment reported type-II multiferroicity in monolayer (ML) NiI based on a presumed spiral magnetic configuration (Spiral-B), which is, as we found here, under deb…
Realistic Spin Model for Multiferroic NiI
Xuanyi Li, Changsong Xu, Boyu Liu +3
A realistic first-principle-based spin Hamiltonian is constructed for the type-II multiferroic NiI, using a symmetry-adapted cluster expansion method. Besides single ion anisot…
