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…
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…
Optical excitation of single- and multi-mode magnetization precession in Galfenol nanolayers
A. V. Scherbakov, A. P. Danilov, F. Godejohann +9
We demonstrate a variety of precessional responses of the magnetization to ultrafast optical excitation in nanolayers of Galfenol (Fe,Ga), which is a ferromagnetic material with la…
Optically driven spin pumping mediating collective magnetization dynamics in a spin valve structure
A. P. Danilov, A. V. Scherbakov, B. A. Glavin +9
We demonstrate spin pumping, i.e. the generation of a pure spin current by precessing magnetization, without application of microwave radiation commonly used in spin pumping experi…
