Spintronic THz emitters based on NiCu alloys
E. A. Karashtin, I. Yu. Pashen'kin, A. V. Gorbatova +4
We study THz emission from ferromagnet / nonmagnetic material (FM/NM) spintronic nanostructures in which the alloy with different is used as an FM, an NM, or bot…
Effective Magnetic Switching of THz Signal in Planar Structured Spintronic Emitters
Evgeny A. Karashtin, Nikita S. Gusev, Maksim V. Sapozhnikov +5
We demonstrate an efficient swithcable spintronic THz emission from a Co(2nm)/Pt(2nm) bilayer split into a grating of micro- or nanostripes in applied external magnetic field of th…
Nonlinear Optical Effects Due to Magnetization Dynamics In a Ferromagnet
Evgeny A. Karashtin, Tatiana V. Murzina
We theoretically consider magnetization dynamics in a ferromagnetic slab induced by the magnetic field of a strong femtosecond laser pulse. The longitudinal geometry, in which the…
Spin current and second harmonic generation in non-collinear magnetic systems: the hydrodynamic model
E. A. Karashtin, A. A. Fraerman
We report a theoretical study of the second harmonic generation in a noncollinearly magnetized conductive medium with equilibrium spin current. The hydrodynamic model is used to un…
Non-reciprocal light diffraction by a vortex magnetic particle
Evgeny Karashtin
We report a theoretical study of light diffraction by a spherical magnetic particle with a vortex magnetization distribution. It is shown that the intensity of the diffracted light…
Non-reciprocal light scattering by lattice of magnetic vortices
O. G. Udalov, M. V. Sapozhnikov, E. A. Karashtin +6
We report on experimental study of optical properties of two-dimensional square lattice of triangle Co and CoFe nanoparticles with a vortex magnetization distribution. We demonstra…
