Ultrafast inhomogeneous magnetization dynamics analyzed by interface-sensitive nonlinear magneto-optics
Jinghao Chen, Jens Wieczorek, Andrea Eschenlohr +3
We analyze laser-induced ultrafast, spatially inhomogeneous magnetization dynamics of epitaxial Co/Cu(001) films in a 0.4-10 nm thickness range with time-resolved magnetization-ind…
Femtosecond spin current pulses generated by the non-thermal spin-dependent Seebeck effect and interacting with ferromagnets in spin valves
Alexandr Alekhin, Ilya Razdolski, Nikita Ilin +8
Using the sensitivity of magneto-induced second harmonic generation to spin currents (SC), we demonstrate in Fe/Au/Fe/MgO(001) pseudo spin valves the generation of 250 fs-long SC p…
Electronic structure and ultrafast dynamics of FeAs-based superconductors by angle- and time-resolved photoemission spectroscopy
I. Avigo, S. Thirupathaiah, E. D. L. Rienks +17
In this article we review our angle- and time-resolved photoemission studies (ARPES and trARPES) on various ferropnictides.
Nanoscale confinement of ultrafast spin transfer torque exciting non-uniform spin dynamics by femtosecond spin current pulses
Ilya Razdolski, Alexandr Alekhin, Nikita Ilin +5
Spintronics had a widespread impact over the past decades due to transferring information by spin rather than electric currents. Its further development requires miniaturization an…
Doping dependence and electron-boson coupling in the ultrafast relaxation of hot electron populations in Ba(Fe_{1-x}Co_x)_2As_2
I. Avigo, S. Thirupathaiah, M. Ligges +3
Using femtosecond time- and angle-resolved photoemission spectroscopy we investigate the effect of electron doping on the electron dynamics in Ba(Fe_{1-x}Co_x)_2As_2 in a range of…
Multiple particle-hole pair creation in the Fermi-Hubbard model by a pump laser
Nicolai ten Brinke, Manuel Ligges, Uwe Bovensiepen +1
We study the Fermi-Hubbard model in the strongly correlated Mott phase under the influence of a harmonically oscillating electric field, e.g., a pump laser. In the Peierls represen…
