Electrically switchable non-relativistic Zeeman spin splittings in collinear antiferromagnets
Longju Yu, Hong Jian Zhao, Laurent Bellaiche +1
Magnetic or electrical manipulation of electronic spin is elementary for spin-based logic, computing, and memory, where the latter is a low-power manipulation scheme. Rashba-like s…
Anomalous Hall effect from nonlinear magnetoelectric coupling
Longju Yu, Hong Jian Zhao, Yurong Yang +2
The anomalous Hall effect (AHE) is a topology-related transport phenomenon being of potential interest in spintronics, because this effect enables the efficient probe of magnetic o…
Spin Orientation Driven Polarization in Collinear Magnets
Yixun Zhang, Longju Yu, Yizhou Tong +4
In a collinear magnet, the predominant magnetic moments are collectively aligned along a specific spatial orientation, and this alignment may yield intriguing phenomena such as spi…
The nature of polar distortions in ferroelectrics
Hong Jian Zhao, Laurent Bellaiche, Yanming Ma
Polar distortion, the collective off-center displacements of atoms, is a fingerprint of a ferroelectric that governs its properties and functionalities. Since the 1970s, the concep…
