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…
Quasi-static strain governing ultrafast spin dynamics
Y. Shin, M. Vomir, D. -H. Kim +3
The quasi-static strain (QSS) is the product generated by the lattice thermal expansion after ultrafast photo-excitation and the effects of thermal and QSS are inextricable. Nevert…
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…
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…
