Dimensional crossover and local strain induced deflection of the spin spiral state in multiferroic NiI2
Tianxing Jiang, Lianchuang Li, Haiyan Zhu +10
Low-dimensional multiferroics hold great promise for integrated magnetoelectric devices. Spin spiral state has recently been shown to induce ferroelectricity in single-layer van de…
Switchable Altermagnetism via Spin-Induced Improper Polarization
Zhihao Dai, Michele Reticcioli, Wei Ren +2
Enabling reversible spin-splitting switching in stray-field-free altermagnets is promising for spintronic applications, but currently limited to a narrow class of polar materials.…
General Theory for Ferroelectric Control of Spin Splitting in Collinear Antiferromagnets
Zhihao Dai, Yingwei Chen, Junyi Ji +2
Electrical control of magnetism is crucial for next-generation spintronics. While recent advances have demonstrated ferroelectric switching in two-dimensional magnets, a general de…
Microscopic evidence of spin-driven multiferroicity and topological spin textures in monolayer NiI2
Haitao Wang, Tianxing Jiang, Weiyi Pan +12
In type II multiferroics, noncollinear spin textures are expected to induce electric polarization directly, leading to strong magnetoelectric coupling. Realizing such spin driven m…
Revealing Higher-Order Topological Bulk-boundary Correspondence in Bismuth Crystal with Spin-helical Hinge State Loop and Proximity Superconductivity
D. M. Zhao, Y. Zhong, T. Yuan +7
Topological materials are typically characterized by gapless boundary states originated from nontrivial bulk band topology, known as topological bulk-boundary correspondence. Recen…
A Universal Spin-Orbit-Coupled Hamiltonian Model for Accelerated Quantum Material Discovery
Yang Zhong, Rui Wang, Xingao Gong +1
The accurate modeling of spin-orbit coupling (SOC) effects in diverse complex systems remains a significant challenge due to the high computational demands of density functional th…
