Role of spatiotemporal nonuniformities in laser-induced magnetization precession damping
P. I. Gerevenkov, Ia. A. Filatov, L. A. Shelukhin +2
Laser-induced magnetization precession measurements in ferromagnets often reveal an anomalous decrease in the damping time near a field-induced second-order spin-orientation transi…
Harnessing magnetic anisotropy for nonlinear magnetization precession and spin waves
P. I. Gerevenkov, L. A. Shelukhin, Ia. A. Filatov +2
The nonlinearity of magnetization precession and spin waves is a cornerstone of contemporary magnonics. We investigate nonlinear magnetization dynamics in a thin epitaxial iron fil…
Switching picosecond magnetoacoustic regimes in a ferromagnetic waveguide
P. I. Gerevenkov, Ia. A. Mogunov, Ia. A. Filatov +4
The development of magnonics requires energy-efficient methods for generating spin waves and controlling their parameters. Acoustic waves are known to resonantly excite spin waves…
Tunable quasi-discrete spectrum of spin waves excited by periodic laser patterns
Ia. A. Filatov, P. I. Gerevenkov, N. E. Khokhlov +1
We present a concept for selective excitation of magnetostatic surface waves with quasi-discrete spectrum using spatially patterned femtosecond laser pulses inducing either ultrafa…
Spatial asymmetry of optically excited spin waves in anisotropic ferromagnetic film
N. E. Khokhlov, Ia. A. Filatov, A. M. Kalashnikova
We analytically discuss and micromagnetically prove the ways to tune the spatial asymmetry of the initial phase, amplitude, and wavevectors of magnetostatic waves driven by ultrafa…
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…
