Topological magnons in Cu2OSeO3

Abstract: Recently, it was predicted topological nature of the magnetic excitations of Cu2OSeO3. It turned out that the system belongs to the class of topologically non-trivial magnets with the appropriate protected gaps in the bulk magnetic spectrum which are closed approaching the boundaries of the crystal. This magnetic Weyl points are presumably caused by the chiral crystal structure. The theory predicts the appearance of the gaps in R and G points at around 12 and 9 meV respectively. The splittings are of the order of 1 meV. It was additionally found that the presence of the DMI causes the Weyl points to move in the K-space in a complicated manner. Here we propose to compare the theoretical predictions with the neutron spectrum.
