Electrical Regulation of Transverse Spin Currents in Unconventional Magnetic Ferroeletrics
Yudi Yang, Zhuang Qian, Ruichun Xiao +4
We identify hexagonal YMnO as a material realization of the elusive -phase of unconventional magnetism, a noncollinear, noncoplanar antiferromagnetic state defined by intrin…
Distinguish the Orientation of Sliding Ferroelectricity by Second-Harmonic Generation
Fengfeng Ye, Qiankun Li, Zhuocheng Lu +5
As the emerging ferroelectric (FE) materials, the ultrathin two-dimensional (2D) sliding ferroelectrics without phase-matching bottleneck, usually exhibit the pronounced second har…
Undamped Soliton-like Domain Wall Motion in Sliding Ferroelectrics
Yubai Shi, Yuxiang Gao, Ri He +3
Sliding ferroelectricity in bilayer van der Waals materials exhibits ultrafast switching speed and fatigue resistance during the polarization switching, offering an avenue for the…
Sliding Flexoelectricity in Two-Dimensional van der Waals Systems
Ri He, Hua Wang, Fenglin Deng +5
Two-dimensional sliding ferroelectrics, with their unique stacking degrees of freedom, offer a different approach to manipulate polarization by interlayer sliding. Bending sliding…
Ferroelastic twin wall mediated ferro-flexoelectricity and bulk photovoltaic effect in SrTiO
Ri He, Haowei Xu, Peijun Yang +3
Ferroelastic twin walls in nonpolar materials can give rise to a spontaneous polarization due to symmetry breaking. Nevertheless, the bi-stable polarity of twin walls and its rever…
