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…
