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…
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…
Defect-Charge-Driven 90° Switching in HfO2
Muting Xie, Hongyu Yu, Zhihao Dai +3
Hafnium dioxide (HfO2) is a CMOS-compatible ferroelectric showing both 180° and 90° switching, yet the microscopic nature of the 90° pathway remains unresolved. We show that the…
