Anisotropic Gyromagnetic Ratio and Orthogonal Einstein-de Haas Effect
Rui Xue, Zhenhua Qiao, Yang Gao +1
We theoretically demonstrate an orthogonal Einstein-de Haas effect, where the rotation of ferromagnetic materials is caused by the change of magnetization in the direction orthogon…
Atomic-scale spin sensing of a 2D -wave altermagnet via helical tunneling
Zhuying Wang, Shuikang Yu, Xingkai Cheng +17
Altermagnetism simultaneously possesses nonrelativistic spin responses and zero net magnetization, thus combining advantages of ferromagnetism and antiferromagnetism. This superior…
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…
Frequency Domain Berry Curvature Effect on Time Refraction
Shiyue Deng, Yang Gao, Qian Niu
We demonstrate that there exist frequency domain Berry curvature in the wave function of photons in dispersive optical systems. This property arises from the frequency dispersion o…
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…
Extrinsic Mechanisms of Phonon Magnetic Moment
Rui Xue, Zhenhua Qiao, Yang Gao +1
We develop a general formalism of phonon magnetic moment by including the relaxation process. We then identify the skew-scattering and side-jump contributions to the phonon magneti…
Magnon Thermal Hall Effect Induced By Symmetric Exchange Interaction
Jikun Zhou, Yang Gao, Qian Niu
By analyzing the spin-group symmetry of magnons, we establish two generalized Onsager's relations in the magnon thermal Hall effect, which reveals the rich and complicated structur…
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…
