Ultrafast coherent THz lattice dynamics coupled to spins in a van der Waals antiferromagnetic flake
Fabian Mertens, David Mönkebüscher, Eugenio Coronado +8
A coherent THz optical lattice mode is triggered by femtosecond laser pulses in the antiferromagnetic van der Waals semiconductor FePS. The 380 nm thick exfoliated flake was pl…
Effect of magnetic anisotropy relaxation on laser-induced magnetization precession in thin galfenol films
P. I. Gerevenkov, D. V. Kuntu, Ia. A. Filatov +6
The rate and pathways of relaxation of a magnetic medium to its equilibrium following excitation with intense and short laser pulses are the key ingredients of ultrafast optical co…
Laser-induced magnetization precession in individual magnetoelastic domains of a multiferroic CoFeB/BaTiO composite
L. A. Shelukhin, N. A. Pertsev, A. V. Scherbakov +5
Using a magneto-optical pump-probe technique with micrometer spatial resolution we show that magnetization precession can be launched in individual magnetic domains imprinted in a…
Electric bias-controlled switching of magnetization of ferrimagnetically coupled Mn delta-layers in a GaAs-AlGaAs quantum well
N. V. Agrinskaya, A. M. Kalashnikova, V. I. Kozub
We suggest a model of synthetic ferrimagnetic semiconductor structure based on GaAs-AlGaAs quantum well doped by two Mn delta-layers. The coupling between the delta-layers is media…
Optical excitation of propagating magnetostatic waves in an epitaxial Galfenol film by an ultrafast magnetic anisotropy change
Nikolai E. Khokhlov, Petr I. Gerevenkov, Leonid A. Shelukhin +6
Using a time-resolved optically-pumped scanning optical microscopy technique we demonstrate the laser-driven excitation and propagation of spin waves in a 20-nm film of a ferromagn…
Ultrafast insulator-to-metal transition in VO nanostructures assisted by picosecond strain pulses
Ia. A. Mogunov, F. Fernández, S. Lysenko +4
Strain engineering is a powerful technology which exploits stationary external or internal stress of specific spatial distribution for controlling the fundamental properties of con…
