Anatomy of ultrafast quantitative magneto-acoustics in freestanding nickel thin films
Antonia Ghita, Tudor-Gabriel Mocioi, Alexey M. Lomonosov +4
We revisit the quantitative analysis of the ultrafast magneto-acoustic experiment in a freestanding nickel thin film by Kim and Bigot [1] by applying our recently proposed approach…
Additive Laser Excitation of Giant Nonlinear Surface Acoustic Wave Pulses
Jude Deschamps, Yun Kai, Jet Lem +6
The laser ultrasonics technique perfectly fits the needs for non-contact, non-invasive, non-destructive mechanical probing of samples of mm to nm sizes. This technique is however l…
Resonant phonon-magnon interactions in free-standing metal-ferromagnet multilayer structures
Urban Vernik, Alexey M. Lomonosov, Vladimir S. Vlasov +5
We analyze resonant magneto-elastic interactions between standing perpendicular spin wave modes (exchange magnons) and longitudinal acoustic phonon modes in free-standing hybrid me…
Anatomy of inertial magnons in ferromagnets
Alexey M. Lomonosov, Vasily V. Temnov, Jean-Eric Wegrowe
We analyze dispersion relations of magnons in ferromagnetic nanostructures with uniaxial anisotropy taking into account inertial terms, i.e. magnetic nutation. Inertial effects are…
Nondestructive femtosecond laser lithography of Ni nanocavities by controlled thermo-mechanical spallation at the nanoscale
V. V. Temnov, A. Alekhin, A. Samokhvalov +3
We present a new approach to femtosecond direct laser writing lithography to pattern nanocavities in ferromagnetic thin films. To demonstrate the concept we irradiated 300~nm thin…
Parametric frequency mixing in the magneto-elastically driven FMR-oscillator
C. L. Chang, A. M. Lomonosov, J. Janusonis +3
We demonstrate the nonlinear frequency conversion of ferromagnetic resonance (FMR) frequency by optically excited elastic waves in a thin metallic film on dielectric substrates. Ti…
Ultrafast Magnetoelastic Probing of Surface Acoustic Transients
J. Janušonis, C. L. Chang, T. Jansma +6
We generate in-plane magnetoelastic waves in nickel films using the all-optical transient grating technique. When performed on amorphous glass substrates, two dominant magnetoelast…
Ultrafast electron-phonon-magnon interactions at noble metal-ferromagnet interfaces
V. Shalagatskyi, O. Kovalenko, V. Shumylo +8
Ultrafast optical excitation of gold-cobalt bilayers triggers the nontrivial interplay between the electronic, acoustic, and magnetic degrees of freedom. Laser-heated electrons gen…
