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…
Plaquette instability competing with bicollinear ground state in detwinned FeTe
David W. Tam, Hsin-Hua Lai, Jin Hu +10
We use inelastic neutron scattering to show that long-range spin waves arising from the static bicollinear antiferromagnetic (AF) order in FeTe, which have twofold rotational symme…
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…
Transverse acoustic phonon anomalies at intermediate wavevectors in MgVO
T. Weber, B. Roessli, C. Stock +7
Magnetic spinels (with chemical formula O, with a 3 transition metal ion) that also have an orbital degeneracy are Jahn-Teller active and hence possess a coupl…
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…
