abstract = {We explore spin dynamics in Cu(1,3-bdc), a quasi-2D
topological magnon insulator. The results show that the
thermal evolution of the Landé g factor (g) is anisotropic:
gin-plane decreases while gout-of-plane increases with
increasing temperature T. Moreover, the anisotropy of the g
factor (Δg) and the anisotropy of saturation magnetization
(ΔMs) are correlated below 4 K, but they diverge above 4 K.
We show that the electronic orbital moment contributes to
the g anisotropy at lower T, while the topological orbital
moment induced by thermally excited spin chirality dictates
the g anisotropy at higher T. Our work suggests an interplay
among topology, spin chirality, and orbital magnetism in
Cu(1,3-bdc).},
