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…
General First-Principles Approach to Crystals in Finite Magnetic Fields
Chengye Lü, Yingwei Chen, Yuzhi Wang +5
We introduce a general first-principles methodology for computing electronic structure in a finite uniform magnetic field which allows for an arbitrary rational magnetic flux and n…
Generation of Pure Spin Current with Insulating Antiferromagnetic Materials
Yingwei Chen, Junyi Ji, Liangliang Hong +2
The generation of pure spin currents is critical for low-dissipation spintronic applications, yet existing methods relying on spin-orbit coupling or ferromagnetic interfaces face c…
Strain-induced gyrotropic effects in ferroelectric BaTiS3
Wei Luo, Asier Zabalo, Guodong Ren +5
Gyrotropic effects, including natural optical activity (NOA) and the nonlinear anomalous Hall effect (NAHE), are crucial for advancing optical and transport devices. We explore the…
Topological interfacial states in ferroelectric domain walls of two-dimensional bismuth
Wei Luo, Yang Zhong, Hongyu Yu +4
Using machine learning methods, we explore different types of domain walls in the recently unveiled single-element ferroelectric, the bismuth monolayer [Nature 617, 67 (2023)]. Rem…
