The complete micromagnetic characterization of asymmetrically sandwiched ferromagnetic films
M. Kopte, U. K. Rößler, R. Schäfer +10
The magnetic properties of ferromagnetic thin films down to the nanoscale are ruled by the exchange stiffness, anisotropies and the effects of magnetic fields. As surfaces break in…
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…
Detection of shorter-than-skin-depth acoustic pulses in a metal film via transient reflectivity
K. J. Manke, A. A. Maznev, C. Klieber +6
The detection of ultrashort laser-generated acoustic pulses at a metal surface and the reconstruction of the acoustic strain profile are investigated. A 2 ps-long acoustic pulse ge…
