Summary: This study demonstrates that the tooth spacing of the magnonic frequency comb in ferromagnetic thin films can be effectively modulated by introducing biaxial in-plane strain, where compressive strain increases the spacing while tensile strain decreases it. This modulation is attributed to the strain-dependent magnetocrystalline anisotropy, with larger spacing leading to higher exchange energy and lower magnetoelastic and anisotropy energies. Furthermore, when the biaxial in-plane strain becomes nonequally axial (or anisotropic), the tooth spacing decreases along with the magnetoelastic energy.

Summary: MnBi2Te4 is a van der Waals material with both topological electron bands and magnetic order. The study shows that magnetic fluctuations increase as the thickness of the samples decreases, indicating a less robust magnetic order. In a bilayer with non-trivial topology, the characteristics of the magnons change as an external magnetic field tunes the ground state.

Summary: The recent discoveries of 2D magnets and their stacking into van der Waals structures have expanded the understanding of 2D phenomena. In this study, strong magnon-exciton coupling is observed in the 2D A-type antiferromagnetic semiconductor CrSBr. Coherent magnons launched by above-gap excitation modulate the exciton energies. These coherent 2D magnons have the potential to be used in optically accessible spintronics, magnonics, and quantum interconnects.

Summary: In this study, two-dimensional magnons were directly observed in atomically thin CrI3 using magneto-Raman spectroscopy, revealing optical selection rules and magnetic properties. The phonon magnon mode in monolayers exhibited strict selection rules, while the optical magnon modes in bilayers and bulk materials were influenced by layer index. Additionally, two degenerate optical magnon modes with opposite angular momentum and conjugate optical selection rules were resolved in layered antiferromagnetic states.

Summary: Magnetic excitations in van der Waals materials, particularly in the 2D limit, have been studied using temperature-dependent magnetoRaman spectroscopy. The researchers identified hybridization of two-magnon excitations with two phonons in manganese phosphorus triselenide, and constructed a model to explain the observations. This work demonstrates the strong hybridization between phonons and a two-magnon continuum, providing insight into interactions in 2D magnetic materials.

Summary: The discovery of ferromagnetic ordering in monolayers of CrSBr, as well as the antiferromagnetic coupling in multilayers, highlights the unique magnetic properties of this 2D material. The Neel temperature of CrSBr increases with decreasing layer number, setting it apart from other 2D magnets. These findings introduce CrSBr as an exciting 2D magnetic semiconductor with potential applications in magnetic-electronic coupling and toroidal moments.

Summary: Interlayer hybridization in 2D van der Waals materials can change their properties, such as the coupling in CrSBr which can be changed by switching the magnetic order. The stacking of monolayers of 2D materials can introduce new properties, like moire bands and highly correlated electronic states.

Summary: In FePS3, strong coupling between magnons and phonons was directly observed using magneto-Raman spectroscopy at magnetic fields up to 30 Tesla. A hybridized magnon-phonon quasiparticle formed due to field-driven resonance with a nearby phonon mode. The polarized Raman results demonstrated the transfer of spin angular momentum from magnons to phonons, generating phonon spin through strong coupling.
