Non-reciprocal spin excitations across the skyrmion-paramagnetic phase transition in MnSi
Tobias Weber, Karin Schmalzl, Johannes Waizner +3
The magnetic excitations of the skyrmion lattice in MnSi comprise a multitude of individual modes, which are non-reciprocal and thereby propagate unidirectionally. We report inelas…
Topological magnon band structure of emergent Landau levels in a skyrmion lattice
T. Weber, D. M. Fobes, J. Waizner +16
The motion of a spin excitation across topologically non-trivial magnetic order exhibits a deflection that is analogous to the effect of the Lorentz force on an electrically charge…
Polarized inelastic neutron scattering of non-reciprocal spin waves in MnSi
Tobias Weber, Johannes Waizner, Paul Steffens +4
We report spin-polarized inelastic neutron scattering of the dynamical structure factor of the conical magnetic helix in the cubic chiral magnet MnSi. We find that the spectral wei…
Propagating spin excitations along skyrmion strings
S. Seki, M. Garst, J. Waizner +6
Magnetic skyrmions, topological solitons characterized by a two-dimensional swirling spin texture, have recently attracted attention as stable particle-like objects. In a three-dim…
Non-reciprocal magnons in non-centrosymmetric MnSi
Tobias Weber, Johannes Waizner, Gregory S. Tucker +7
Using two cold-neutron triple-axis spectrometers we have succeeded in fully mapping out the field-dependent evolution of the non-reciprocal magnon dispersion relations in all magne…
Field dependence of non-reciprocal magnons in chiral MnSi
Tobias Weber, Johannes Waizner, Gregory Tucker +6
Spin waves in chiral magnetic materials are strongly influenced by the Dzyaloshinskii-Moriya interaction resulting in intriguing phenomena like non-reciprocal magnon propagation an…
Low spin wave damping in the insulating chiral magnet CuOSeO
I. Stasinopoulos, S. Weichselbaumer, A. Bauer +6
Chiral magnets with topologically nontrivial spin order such as Skyrmions have generated enormous interest in both fundamental and applied sciences. We report broadband microwave s…
Linearly polarized GHz magnetization dynamics of spin helix modes in the ferrimagnetic insulator CuOSeO
I. Stasinopoulos, S. Weichselbaumer, A. Bauer +5
Linear dichroism -- the polarization dependent absorption of electromagnetic waves -- is routinely exploited in applications as diverse as structure determination of DNA or polariz…
Collective spin excitations of helices and magnetic skyrmions: review and perspectives of magnonics in non-centrosymmetric magnets
Markus Garst, Johannes Waizner, Dirk Grundler
Magnetic materials hosting correlated electrons play an important role for information technology and signal processing. The currently used ferro-, ferri- and antiferromagnetic mat…
Band structure of helimagnons in MnSi resolved by inelastic neutron scattering
M. Kugler, G. Brandl, J. Waizner +8
A magnetic helix realizes a one-dimensional magnetic crystal with a period given by the pitch length . Its spin-wave excitations -- the helimagnons -- experience Bragg scatter…
