Windmill Spin Dynamics and Its Induced Anomalous Hall Effect in Noncollinear Antiferromagnet Mn3Sn
Jikun Zhou, Yang Gao, Qian Niu
We demonstrate that the spin dynamics of the noncollinear antiferromagnet Mn3Sn hosts a soft eigenmode that transitions from small-angle oscillation to a large-angle, chiral windmi…
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…
Ward identities and orbital magnetization in current density functional theory
Giovanni Vignale, Junren Shi, Di Xiao +1
We revisit the derivation of the orbital magnetization formula for periodic crystals in current density functional theory (CDFT)[1]. Our new derivation computes the linear response…
Magic of nonlocal geometric force: lighting up optical transition and transporting angular momentum by chiral phonons
Hao Chen, Haoshu Li, Lifa Zhang +1
We investigate the impact of the nonlocal geometric force -- arising from the molecular Berry curvature -- on the lattice dynamics of magnetic materials with broken time-reversal s…
