Pronounced in-plane anomalous Hall effect with vanishing out-of-plane response in Cr1.2Te2
Wenzhi Peng, Zheng Liu, ShaSha Wang +8
We report an unconventional anomalous Hall regime in the van der Waals ferromagnet Cr1.2Te2, in which the anomalous Hall effect (AHE) is present for in-plane magnetization but abse…
Magnon-Driven Anomalous Hall Effect in Altermagnets
Zheng Liu, Yang Gao, Qian Niu
We propose a magnon-driven anomalous Hall effect in altermagnets, arising from the coupling between coherently excited chiral magnons and chiral electronic motion. Using density-ma…
Experimental Evidence of Néel-order-driven Magneto-optical Kerr Effect in an Altermagnetic Insulator
Haolin Pan, Rui-Chun Xiao, Jiahao Han +5
The magneto-optical Kerr effect (MOKE) is investigated in hematite, a collinear antiferromagnetic insulator, across a broad wavelength spectrum. By combining the optical measuremen…
Rigid-Body Anisotropy in Noncollinear Antiferromagnets
Zheng Liu, Yang Gao, Qian Niu
Characterizing the anisotropic structure in noncollinear antiferromagnets is essential for antiferromagnetic spintronics. In this work, we provide a microscopic theory linking the…
Pairing-induced Momentum-space Magnetism and Its Implication In Optical Anomalous Hall Effect In Chiral Superconductors
Bin Geng, Yang Gao, Qian Niu
The intrinsic mechanisms of the magneto-optical Kerr signal in chiral superconductors often involve multi-orbital degree of freedom. Here by considering a generic single-orbital an…
Orthogonal Geometry of Magneto-Optical Kerr Effect Enabled by Magnetization Multipole of Berry Curvature
Haolin Pan, Han Li, Jixiang Huang +17
The Magneto-Optical Kerr Effect (MOKE) is a fundamental tool in magnetometry, pivotal for advancing research in optics, magnetism, and spintronics as a direct probe of magnetizatio…
Multipolar Anisotropy in Anomalous Hall Effect from Spin-Group Symmetry Breaking
Zheng Liu, Mengjie Wei, Dazhi Hou +2
Traditional view of the anomalous Hall effect~(AHE) in ferromagnets is that it arises from the magnetization perpendicular to the measurement plane and that there is a linear depen…
Observation of the In-plane Anomalous Hall Effect induced by Octupole in Magnetization Space
Wenzhi Peng, Zheng Liu, Haolin Pan +9
The Anomalous Hall Effect (AHE) manifests as a transverse voltage proportional to magnetization in ferromagnetic materials under the application of a charge current, being an indis…
Infrared Imaging of Magnetic Octupole Domains in Non-collinear Antiferromagnets
Peng Wang, Wei Xia, Jinhui Shen +12
Magnetic structure plays a pivotal role in the functionality of antiferromagnets (AFMs), which not only can be employed to encode digital data but also yields novel phenomena. Desp…
