“…(e) Interlayer exchange field, HE, calculated at different temperatures from the fitting of the curves for two modes to the mentioned model; the values have been derived for magnetic field applied at ψ ≈ 0 • , 25 cedure provided in Supplementary section IV) of the two branches for ψ ≈ 55 • and T ≈ 1.5 K. The magnitude of exchange field agrees with previous observations in antiferromagnetic systems [15,16,28]. In addition, a decreasing trend is seen in the interlayer exchange field as a function of temperature similar to other systems [29,30]. As the temperature is increased from 1.5 K to 10 K, the interlayer exchange field reduces by ≈ 30%.…”

Spin-waves have been studied for data storage, communication and logic circuits in the field of spintronics based on their potential to substitute electrons [1,2]. Recent discovery of magnetism in two-dimensional (2D) systems such as monolayer CrI3 and Cr2Ge2Te6 has led to a renewed interest in such applications of magnetism in the 2D limit [3][4][5]. Here we present direct evidence of standing spin-waves along with the uniform precessional resonance modes in van der Waals magnetic material, CrCl3. Our experiment is the first direct observation of standing spin-wave modes, set up across a thickness of 20 µm, in a van der Waals material. We detect standing spin-waves in the vicinity of both, optical and acoustic, branches of the antiferromagnetic resonance. We also observe magnon-magnon coupling, softening of resonance modes with temperature and extract the evolution of interlayer exchange field as a function of temperature.

Spin waves are studied for data storage, communication, and logic circuits in the field of spintronics based on their potential to substitute electrons. The recent discovery of magnetism in 2D systems such as monolayer CrI3 and Cr2Ge2Te6 has led to a renewed interest in such applications of magnetism in the 2D limit. Here, direct evidence of standing spin waves is presented along with the uniform precessional resonance modes in the van der Waals magnetic material, CrCl3. This is the first direct observation of standing spin‐wave modes, set up along a thickness of 20 mm, in a van der Waals material. Standing spin waves are detected in the vicinity of both branches, optical and acoustic, of the antiferromagnetic resonance. Magnon–magnon coupling and softening of resonance modes with temperature enable extraction of interlayer exchange field as a function of temperature.

“…The acoustic (optical) mode is excited by perpendicular (parallel) configuration between microwave and applied magnetic fields. There are a number of reports in which these two modes in different SyAFs have been studied in great detail [24][25][26][27][28]. For example, mutual spin pumping within the coupled moments has been proposed [29][30][31] and experimentally demonstrated [32][33][34][35].…”
