A crystal structure that cannot be superposed on its mirror image by any combination of rotations and translations is classified as chiral. Such crystal structures have gained importance in recent years since they are prone to host unconventional magnetic orders and to exhibit topological magnetic textures. These properties result from the Dzyaloshinskii-Moriya antisymmetric exchange interaction which is authorized when space inversion is broken. While recent reports have shown the muon spin…

Absence of local moments in the kagome metal KV3Sb5 as determined by muon spin spectroscopy

We have carried out muon spin relaxation and rotation measurements on the newly discovered kagome metal KV3Sb5, and find a local field dominated by weak magnetic disorder which we associate with the

Theory of helical magnetic structures and phase transitions in MnSi and FeGe

The long-period helical magnetic structures in MnSi and FeGe are shown to be consequences of a ferromagnetic Dzyaloshinskii instability (1964). Renormalisation group theory predicts the transition to

Anisotropic Superexchange Interaction and Weak Ferromagnetism

A theory of anisotropic superexchange interaction is developed by extending the Anderson theory of superexchange to include spin-orbit coupling. The antisymmetric spin coupling suggested by

We show that zero-field μSR depolarisation rate measurements on dipolar Heisenberg paramagnets near the Curie temperature can give information on the longitudinal and transverse spin fluctuations.
