报告摘要：The emergence of magnetism in two-dimensional (2D) van der Waals (vdW) materials has ignited a new realm of profound inquiries into magnetism. In this presentation, we delve into the magnetization and spin dynamics of 2D magnets through the employment of highly responsive broadband ferromagnetic resonance spectroscopy (FMR). Our investigations involve emergent magnets such as Fe5GeTe2, CrTe2 which are room-temperature van der Waals magnets, and Cu(1,3-bdc), a quasi-2D Kagome lattice magnet. By harnessing the superior qualities of high-quality factor superconducting resonators, our FMR studies unveil a temperature-dependent Landé g-factor, hinting at the pertinence of orbital moments in these materials. Furthermore, our linewidth analyses reveal intriguing spin scattering mechanisms within van der Waals magnets, underscoring their distinctive properties compared to conventional magnets. We also introduce intriguing domain dynamics inherent to van der Waals magnets through ferromagnetic resonance. Our experiments furnish vital insights into the magnetic states and spin scattering processes in 2D magnets, paving the way for the development of spintronic devices based on 2D magnetism.
