Dirac nodal line magnons in layered honeycomb antiferromagnets.

S. A. Owerre

We show the existence of three-dimensional (3D) Dirac nodal line (DNL) magnons in layered honeycomb antiferromagnets. In stark contrast to 3D ferromagnets, the present DNL magnons are robust against the Dzyaloshinskii-Moriya interaction. They exhibit small dispersive drumhead magnon surface states that connect a pair of surface projection of the DNL magnons, and are topologically protected by magnetic crystal symmetry.
