Tracing the thermal mechanism in femtosecond spin dynamics
U. Atxitia, O. Chubykalo-Fesenko, J. Walowski +2
We compare femtosecond pump-probe experiments in Ni and micromagnetic modelling based on the Landau-Lifshitz-Bloch equation coupled to a two-temperature model, revealing a predomin…

Intrinsic and non-local Gilbert damping in polycrystalline nickel studied by Ti:Sapphire laser fs spectroscopy
J. Walowski, M. Djordjevic Kaufmann, B. Lenk +3
The use of femtosecond laser pulses generated by a Ti:Sapphire laser system allows us to gain an insight into the magnetization dynamics on time scales from sub-picosecond up to 1…

Energy equilibriation processes of electrons, magnons and phonons on the femtosecond timescale
J. Walowski, G. Müller, M. Djordjevic +4
By means of time-resolved Kerr spectroscopy experiments we relate the energy dissipation processes on the femtosecond (electron-spin relaxation time ) and nanosecond tim…
