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…
Unidirectional propagation of spin waves excited by femtosecond laser pulses in a planar waveguide
P. I. Gerevenkov, Ia. A. Filatov, A. M. Kalashnikova +1
Low-energy magnonic logic circuits are an actively developing field of modern magnetism. The potential benefits of magnonics for data processing are vitally dependent on units base…
Spectrum evolution and chirping of laser-induced spin wave packets in thin iron films
Ia. A. Filatov, P. I. Gerevenkov, M. Wang +3
We present the experimental study of ultrafast optical excitation of magnetostatic surface spin wave (MSSW) packets and their spectral properties in thin films of pure iron. As the…
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…
Néel domain wall as a tunable filter for optically excited magnetostatic waves
N. E. Khokhlov, A. E. Khramova, Ia. A. Filatov +3
We present a concept of a tunable optical excitation of spin waves and filtering their spectra in a ferromagnetic film with 180 Néel domain wall. We show by means of micr…
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…
