Odd-Parity Chiral Magnons in Collinear Antiferromagnetic Multiferroics: Symmetry Classification and Ferroelectric Switching
Quanchao Du, Zhenlong Zhang Yuanjun Jin, Rui Li +6
The coupling between ferroelectrics and magnetism presents a promising avenue for low-dissipation spintronic devices. However, such couplings remain rare, and the direct realizatio…
Light-Driven Ferroic Switching Enables Reversible Control of Hydrogen Adsorption Thermodynamics
Xueqing Wan, Zhenlong Zhang, Charles Paillard +5
Reversible ultrafast switching of surface thermodynamics is highly desirable for hydrogen storage and catalysis yet remains elusive at the nanoscale. Here we demonstrate that photo…
Electric-Switchable Chiral Magnons in PT-Symmetric Antiferromagnets
Jinyang Ni, Congzhe Yan, Peiyuan Cui +3
The magnons in antiferromagnetic insulators (AFIs) exhibit dual chirality, each carrying opposite spin angular momentum. However, in PT-symmetric AFIs, the magnon bands remain dege…
Electro-optic effects in some sliding ferroelectrics
Xueqing Wan, Zhenlong Zhang, Charles Paillard +4
Sliding ferroelectrics, which exhibit out-of-plane polarization arising from specific stacking rather than conventional ionic displacements, are new types of ferroelectrics whose u…
Nonreciprocal magnons in layered antiferromagnets VPX3(X =S,Se,Te)
Quanchao Du, Zhenlong Zhang, Jinyang Ni +2
Nonreciprocal magnons, characterized by propagation with differing energies along the k and -k directions, are crucial for modern spintronics applications. However, their realizati…
Topological switching in bilayer magnons via electrical control
Xueqing Wan, Quanchao Du, Jinlian Lu +5
Topological magnons, quantized spin waves featuring nontrivial boundary modes, present a promising route toward lossless information processing. Realizing practical devices typical…
