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…
The effect of dynamical compressive and shear strain on magnetic anisotropy in low symmetry ferromagnetic film
T. L. Linnik, V. N. Kats, J. Jäger +7
Dynamical strain generated upon excitation of a metallic film by a femtosecond laser pulse may become a versatile tool enabling control of magnetic state of thin films and nanostru…
Photo-induced valley currents in strained graphene
T. L. Linnik
The theoretical results are presented showing that strain-induced anisotropy of graphene spectrum gives rise to the valley currents under the illumination by normally incident ligh…
Effective Hamiltonian of Strained Graphene
T. L. Linnik
Based on the symmetry properties of graphene lattice, we derive the effective Hamiltonian of graphene under spatially non-uniform acoustic and optical strains. We show that with th…
Theory of magnetization precession induced by a picosecond strain pulse in ferromagnetic semiconductor (Ga,Mn)As
T. L. Linnik, A. V. Scherbakov, D. R. Yakovlev +3
A theoretical model of the coherent precession of magnetization excited by a picosecond acoustic pulse in a ferromagnetic semiconductor layer of (Ga,Mn)As is developed. The short s…
Electron-phonon interaction via Pekar mechanism in nanostructures
B. A. Glavin, V. A. Kochelap, T. L. Linnik +1
We consider an electron-acoustic phonon coupling mechanism associated with the dependence of crystal dielectric permittivity on the strain (the so-called Pekar mechanism) in nanost…
