- Аннотация: Traditional magnetization dynamics measurements in van der Waals antiferromagnets rely on millimeter-sized crystalsto achieve detectable signal levels. However, conventional approaches become inadequate when investigating micrometerscalefew-layer samples, which host unique layer-dependent phenomena including tunable magnon–magnon interactionsand thickness-controlled mode hybridization. Here, we develop a method enabling ferromagnetic resonance (FMR) measurementson micrometer-sized antiferromagnetic samples (CrCl3) using a conventional vector network analyzer (VNA)-basedFMR setup. Our approach combines a protective polycarbonate (PC) coating to prevent delamination, mechanical damage,and aging-induced degradation, with a precision alignment technique that guarantees stable signal acquisition throughoptimal positioning relative to the excitation source. FMR measurements reveal robust spin dynamics in PC-protectedCrCl3, with clearly resolved acoustic and Kittel modes, showing a reduced interlayer exchange field compared to bulkcrystals. Remarkably, the magnetic properties remained unchanged after 3 months under ambient conditions, confirmingthe effectiveness of the PC coating. Thus, our method enables reliable FMR studies of micrometer-scale van der Waalsmagnets, bridging the gap between bulk and few-layer investigations and paving the way for exploring layer-dependent spinphenomena.
