DOI: 10.1021/acs.nanolett.3c00351
Abstract: Topological phonons and magnons potentially enable low-loss, quantum coherent, and chiral transport of information and energy at the atomic scale. Van der Waals magnetic materials are promising to realize such states due to their recently… read more here.

DOI: 10.1103/physrevb.101.214419
Abstract: We perform thermodynamic and inelastic neutron scattering (INS) measurements to study the lattice dynamics (phonons) of a cubic collinear antiferromagnet ${\mathrm{Cu}}_{3}{\mathrm{TeO}}_{6}$ which hosts topological spin excitations (magnons). While the specific heat and thermal conductivity results… read more here.

Abstract: In this paper, we report the theoretical possibility of generating magnon-polaron excitations through a space-varying magnetic field. The spatial dependence of the magnetic field in the Zeeman interaction gives rise to a magnon-phonon coupling when… read more here.

DOI: 10.1103/physrevb.96.100406
Abstract: The ferrimagnetic insulator yttrium iron garnet (YIG) has been widely used in microwave and spintronic devices. Anomalous features in spin Seeback effect voltages have been observed in Pt/YIG and attributed to magnon-phonon coupling. Using inelastic… read more here.

Abstract: We address the theory of magnon-phonon interactions and compute the corresponding quasiparticle and transport lifetimes in magnetic insulators, with a focus on yttrium iron garnet at intermediate temperatures from anisotropy- and exchange-mediated magnon-phonon interactions, the… read more here.

DOI: 10.1103/physreve.106.024122
Abstract: Using Green's function method, we study thermal transport properties of magnons transmitting through a magnetic nanowire at a certain temperature. In a small part of the nanowire in the middle, we are supposed to have… read more here.
