Abstract: A temperature-dependent approach involving Green-Kubo equilibrium atomic and spin dynamics (GKEASD) is reported to assess phonon and magnon thermal transport processes accounting for phonon-magnon interactions. Using body-centered cubic (BCC) iron as a case study, GKEASD… read more here.

DOI: 10.1103/physrevb.104.064305
Abstract: We develop a phonon-magnon interaction model for the two-dimensional honeycomb ferromagnet and calculate the band structure of the hybrid phonon-magnon excitation. When the phonon (either acoustic or optical) energy overlaps with the magnon energy, the… read more here.
