Magnon nodal-line semimetals and drumhead surface states in anisotropic pyrochlore ferromagnets
Alexander Mook, Jürgen Henk, Ingrid Mertig
We introduce a new type of topological magnon matter: the magnonic pendant to electronic nodal-line semimetals. Magnon spectra of anisotropic pyrochlore ferromagnets feature twofol…

Tunable magnon Weyl points in ferromagnetic pyrochlores
Alexander Mook, Jürgen Henk, Ingrid Mertig
The dispersion relations of magnons in ferromagnetic pyrochlores with Dzyaloshinskii-Moriya interaction is shown to possess Weyl points, i.\,e., pairs of topological nontrivial cro…
