Observation and Control of the Magnetic Photogalvanic Effect from Strongly Bound Excitons
Xianfan Nie, Tarun Patel, Hyunggeun Lee +11
Photogalvanic effects arising from the quantum geometry of noncentrosymmetric materials are promising for next-generation light-harvesting devices that do not require a built-in el…
Emergent Atomic Scale Polarisation Vortices in BaTiS3
Boyang Zhao, Gwan Yeong Jung, Shantanu Singh +21
Topological defects, such as vortices and skyrmions in magnetic and dipolar systems, can give rise to properties that are not observed in typical magnets and dielectrics. Here, we…
Tuning Coupled Toroidic and Polar Orders in a Bilayer Antiferromagnet
Chuangtang Wang, Xiaoyu Guo, Zixin Zhai +5
Magnetic toroidal order features a loop-like arrangement of magnetic dipole moments, thus breaking both spatial inversion (P) and time-reversal (T) symmetries while preserving thei…
Direct observation of distinct bulk and edge nonequilibrium spin accumulation in ultrathin MoTe
Fangchu Chen, Kamal Das, Bowen Yang +11
Low-symmetry two-dimensional (2D) topological materials such as MoTe host efficient charge-to-spin conversion (CSC) mechanisms that can be harnessed for novel electronic and sp…
Nanoscale quantum imaging of field-free deterministic switching of a chiral antiferromagnet
Jingcheng Zhou, Senlei Li, Chuangtang Wang +11
Recently, unconventional spin-orbit torques (SOTs) with tunable spin generation open new pathways for designing novel magnetization control for cutting-edge spintronics innovations…
Visualizing Field-free Deterministic Magnetic Switching of all-van der Waals Spin-Orbit Torque System Using Spin Ensembles in Hexagonal Boron Nitride
Xi Zhang, Jingcheng Zhou, Chaowei Hu +19
