Electrically-gated laser-induced spin dynamics in magneto-electric iron garnet at room temperature
T. T. Gareev, N. E. Khokhlov, L. Körber +2
Ultrafast pump-probe imaging reveals that the efficiency of optical excitation of coherent spins waves in epitaxial iron garnet films can be effectively controlled by an external e…
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…
Strongly inhomogeneous spin dynamics induced by ultrashort laser pulses with a gradient intensity profile
T. T. Gareev, N. E. Khokhlov, L. Körber +1
The optical pump-probe technique is a common tool for investigation of ultrafast spin dynamics, which usually utilizes single-diode detection averaging the dynamics over the pumped…
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…
Double pulse all-optical coherent control of ultrafast spin-reorientation in antiferromagnetic rare-earth orthoferrite
N. E. Khokhlov, A. E. Dolgikh, B. A. Ivanov +1
A pair of circularly polarized laser pulses of opposite helicities are shown to control the route of spin reorientation phase transition in rare-earth antiferromagnetic orthoferrit…
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…
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…
Protected Long-Distance Guiding of Hypersound Underneath a Nano-Corrugated Surface
Dmytro D. Yaremkevich, Alexey V. Scherbakov, Serhii M. Kukhtaruk +13
Within a new paradigm for communications on the nanoscale, high-frequency surface acoustic waves are becoming effective data carrier and encoder. On-chip communications require aco…
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…
