Odd-Parity Chiral Magnons in Collinear Antiferromagnetic Multiferroics
Quanchao Du, Zhenlong Zhang, Zhenlong Zhang Yuanjun Jin +9
Odd-parity magnetism represents an intriguing frontier in unconventional magnets; however, its realization has traditionally relied on noncollinear magnetic orders accompanied by b…
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…
Ferroelectric Switchable Topological Magnon Hall Effect in Type-I Multiferroics
Quanchao Du, Jinlian Lu, Xueqing Wan +2
Electric control of magnetism at room temperature is crucial for developing next-generation, low-power spintronic devices. However, the intrinsic incompatibility between ferroelect…
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…
