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

Dual nature of magnetism in MnSi

The temperature dependence of the manganese magnetic moment and the spin-lattice relaxation rate measured by the muon spin relaxation technique in the magnetically ordered phase of the chiral

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

Probing longitudinal and transverse spin dynamics of paramagnets near TC by zero-field μSR measurements

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.

Critical fluctuations in MnSi nearTC: A polarized neutron scattering study

Results of polarized neutron small angle scattering in MnSi, a cubic itinerant magnet, near ${T}_{c}=28.8\phantom{\rule{0.3em}{0ex}}\mathrm{K}$ are presented and analyzed. The diffuse scattering

Interplay between crystalline chirality and magnetic structure in Mn 1 − x Fe x Si

X-ray diffraction using synchrotron radiation and polarized neutron small-angle diffraction have been used to evaluate the absolute crystallographic structure and the spin helix chirality of

Polarization Effects in the Magnetic Elastic Scattering of Slow Neutrons

The theory of the elastic scattering of polarized neutrons by magnetic crystals with ordered spins is developed. Several terms which were omitted by Halpern and Johnson in their original treatment of

Magnetic Properties of the Monosilicides of Some 3d Transition Elements

Motivated by the recent observation1 of the unusual electronic properties of FeSi, as manifested in the 57Fe Mossbauer effect and 29Si NMR, the magnetic susceptibilities of the monosilicides of Cr,
