Role of intersublattice exchange interaction on ultrafast longitudinal and transverse magnetization dynamics in Permalloy
A. Maghraoui, F. Fras, M. Vomir +4
We report about element specific measurements of ultrafast demagnetization and magnetization precession damping in Permalloy (Py) thin films. Magnetization dynamics induced by opti…
Single shot all optical switching of intrinsic micron size magnetic domains of a Pt/Co/Pt ferromagnetic stack
Mircea Vomir, Michèle Albrecht, Jean-Yves Bigot
We demonstrate that the magnetization reversal in a ferromagnetic Pt/Co/Pt stack can be induced by a single femtosecond laser pulse. We find that the size of the switched spot is c…
Magnetization reversal in isolated and interacting single-domain nanoparticles
H. Kesserwan, G. Manfredi, J. -Y. Bigot +1
Computational and experimental results on the thermally-induced magnetization reversal in single-domain magnetic nanoparticles are reported. The simulations are based on the direct…
Ultrafast Magneto-Acoustics in Nickel Films
Ji-Wan Kim, Mircea Vomir, Jean-Yves Bigot
We report about the existence of magneto-acoustic pulses propagating in a 200-nm-thick ferromagnetic nickel film excited with 120 fs laser pulses. They result from the coupling bet…
How do spins interact coherently with ultrashort laser pulses ?
Hélène Vonesch, Jean-Yves Bigot
We investigate the interaction of femtosecond laser pulses with spins including relativistic corrections. The time-ordered magneto-optical signals corresponding to a pump-probe con…
