Spurious spin nutation modes arising from truncated memory effects
Markus Weißenhofer, Ritwik Mondal, M. S. Mrudul +1
Spin dynamics is conventionally treated as inertia-free. The inertial Landau-Lifshitz-Gilbert equation (iLLG) extends this with a second-order time derivative, predicting a high-fr…
A crystal-field route to THz-driven magnetization
T. Zalewski, M. S. Mrudul, Y. Lee +5
Light carries angular momentum, but the microscopic pathways that transform it into magnetization remain elusive. Here we establish that crystal-field excitations, historically vie…
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…
Generation of Phonons with Angular Momentum During Ultrafast Demagnetization
M. S. Mrudul, Markus Weißenhofer, Peter M. Oppeneer
A major question in the field of femtosecond laser-induced demagnetization is whereto the angular momentum lost by the electrons is transferred. Recent ultrafast electron diffracti…
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…
Spin-lattice couplings in ferromagnets: analysis from first-principles
I. P. Miranda, M. Pankratova, M. Weißenhofer +8
Magnetoelasticity plays a crucial role in numerous magnetic phenomena, including magnetocalorics, magnon excitation via acoustic waves, and ultrafast demagnetization/Einstein-de Ha…
