Magnetic Field Control of the Néel Vector and Magnon Visibility in Altermagnetic MnTe
Tobias Weber, Niclas Heinsdorf, Shane Smolenski +11
Altermagnetic order gives rise to momentum-dependent spin splitting of electronic and magnonic excitations even in the absence of a net magnetization. Here, we investigate the magn…

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…

Non-Reciprocal Zone Boundary Magnon Propagation in CuOSeO
Tobias Weber, Niclas Heinsdorf, Michal Stekiel +3
Inelastic neutron scattering in the chiral magnet CuOSeO reveals strong non-reciprocal effects on magnon propagation at the boundary of the nuclear Brillouin zone. The non-…
