Tunnel-Barrier-Engineered Ultrafast Demagnetization and Spin Transport in Graphene-Based Heterostructures
Suchetana Mukhopadhyay, David Muradas-Belinchon, Francesco Foggetti +3
Heterostructures combining graphene with 3d transition metal ferromagnets (FMs) enable various spin-based phenomena at ultrafast timescales. However, challenges such as the interfa…
Anatomy of spin-orbit-torque-assisted magnetization dynamics in Co/Pt bilayers: Importance of the orbital torque
Harshita Devda, András Deák, Leandro Salemi +4
Understanding the mechanism driving magnetization switching in spin-orbit-torque-assisted devices remains a subject of debate. While originally attributed to the spin Hall effect a…
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…
Cavity-assisted magnetization switching in a quantum spin-phonon chain
Mohsen Yarmohammadi, Peter M. Oppeneer, James K. Freericks
We propose a Néel magnetization switching mechanism in a hybrid magnon-phonon optical cavity system. A terahertz-pumped single-mode cavity photon couples to a spin-phonon chain, wh…
Quantitative modeling of spintronic terahertz emission due to ultrafast spin transport
Francesco Foggetti, Peter M. Oppeneer
In spintronic terahertz emitters, THz radiation is generated by exciting an ultrafast spin current through femtosecond laser excitation of a ferromagnetic-nonmagnetic metallic hete…
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…
