Thermal Evolution of Dirac Magnons in the Honeycomb Ferromagnet CrBr${}_3$

S. E. Nikitin, B. Fåk, K. W. Krämer +4

CrBr${}_3$ is an excellent realization of the two-dimensional honeycomb ferromagnet, which offers a bosonic equivalent of graphene with Dirac magnons and topological character. We pe…
