Femtosecond Photocurrents at the Pt/FeRh Interface
Rajasekhar Medapalli, Guanqiao Li, Sheena K. K. Patel +4
Femtosecond laser excitation of FeRh/Pt bilayers launches an ultrafast pulse of electric photocurrent in the Pt-layer and thus results in emission of electromagnetic radiation in t…
Spin-current-mediated rapid magnon localisation and coalescence after ultrafast optical pumping of ferrimagnetic alloys
E. Iacocca, T-M. Liu, A. H. Reid +31
Sub-picosecond magnetisation manipulation via femtosecond optical pumping has attracted wide attention ever since its original discovery in 1996. However, the spatial evolution of…
Laser induced THz emission from femtosecond photocurrents in Co/ZnO/Pt and Co/Cu/Pt multilayers
G. Li, R. V. Mikhaylovskiy, K. A. Grishunin +3
The ultrashort laser excitation of Co/Pt magnetic heterostructures can effectively generate spin and charge currents at the interfaces between magnetic and nonmagnetic layers. The…
Laser-driven quantum magnonics and THz dynamics of the order parameter in antiferromagnets
D. Bossini, S. Dal Conte, O. Gomonay +8
The impulsive generation of two-magnon modes in antiferromagnets by femtosecond optical pulses, so-called femto-nanomagnons, leads to coherent longitudinal oscillations of the anti…
Generation of single skyrmions by picosecond magnetic field pulses
Vegard Flovik, Alireza Qaiumzadeh, Ashis K. Nandy +2
We numerically demonstrate an ultrafast method to create skyrmions in a ferromagnetic sample by applying a picosecond (effective) magnetic fi…
Switching of chiral magnetic skyrmions by picosecond magnetic field pulses via transient topological states
Changhoon Heo, Nikolai S. Kiselev, Ashis Kumar Nandy +2
Magnetic chiral skyrmions are vortex like spin structures that appear as stable or meta-stable states in magnetic materials due to the interplay between the symmetric and antisymme…
