Piezo-Kerr effect in altermagnets and noncollinear antiferromagnets
Yuqi Liu, Qiu-Shi Huang, Xinfeng Chen +4
Symmetry is usually viewed as a constraint on physical responses, but it can also be used to design the fields that control them. Here, we adopt the representation-matching princip…
Anomalous Transverse Response and Multi-Field Ferrialtermagnetic-Ferroelectric Valve with CrSb Flakes
Long Zhang, Xinfeng Chen, Hongfei Liang +5
Altermagnets combine the zero-stray-field of antiferromagnets with the spin polarization of ferromagnets, showing great potential for spintronic applications. Here, we propose ferr…
Two-dimensional vertically polarized Hg3AsSe4I monolayer for efficient photocatalytic water-splitting: promoting carrier separation by intrinsic electric field and Rashba effect
Xinfeng Chen, Wenchao Shan, Fengfeng Ye +1
Efficient separation of photo-excited electron-hole pairs is essential for developing the high performance photocatalysts towards light-driven water-splitting applications. To this…
Nonmagnetic-magnetic Transitions in Rutile RuO2
Yue-Fei Hou, Siyuan Liu, Wanxiang Fen +4
Rutile RuO has recently attracted great interest, as its magnetic ground state remains controversial. Experimental studies have reported either nonmagnetic (NM) or altermagneti…
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…
Unconventional Magnetism, Sliding Ferroelectricity, and Magneto-Optical Kerr Effect in Multiferroic Bilayers
Chen Xinfeng, Ding Ning, Paolo Barone +6
Antiferromagnetic (AFM) materials provide a platform to couple altermagnetic (AM) spin-splitting with the magneto-optical Kerr effect (MOKE), offering potential for next-generation…
