Symmetry-Enforced Chiral Phonons in Altermagnets via Magnon-Phonon Coupling
Philipp Rieger, Markus Weißenhofer, Sergiy Mankovsky +1
Chiral phonons are attractive for spintronics applications, however, their zero-field generation in conventional antiferromagnets is forbidden by combined parity and time-reversal…
Symmetry-Selective Topological Magnon Engineering by Phonon Angular Momentum
Markus Weißenhofer, Philipp Rieger, Chandan K. Singh +3
Dynamical control of Berry curvature remains an outstanding challenge in the engineering of topological phases. Here, we demonstrate control of magnon band structures via coherentl…
Chiral Phonons Arising From Chirality-Selective Magnon-Phonon Coupling
Markus Weißenhofer, Philipp Rieger, M. S. Mrudul +3
Chiral phonons are desirable for applications in spintronics but their generation and control remains a challenge.Here we demonstrate the emergence of truly chiral phonons from sel…
Defect-enhanced diffusion of magnetic skyrmions
Philipp Rieger, Markus Weißenhofer, Ulrich Nowak
Defects, i.e. inhomogeneities of the underlying lattice, are ubiquitous in magnetic materials and can have a crucial impact on their applicability in spintronic devices. For magnet…
