Probing ultrafast magnetization thanks to ultrashort soft X-ray pulses — •Emmanuelle Jal — Sorbonne Université, CNRS, Laboratoire de Chimie Physique - Matière et Rayonnement, LCPMR, Paris 75005, France

Even after more than 25 years of studies and debates, the mechanisms of ultrafast demagnetization remain disputed. In order to bring new experimental information into this field, and with the advent of femtosecond X-rays sources, new time-resolved XUV and soft X-ray-based pump/probe techniques are performed on magnetic thin films. During this talk, I will give an overview of what can be done with XUV and soft x-ray short pulses to probe electronic, magnetic, and structural dynamics. A special emphasis will be given to (i) simultaneous electronic and magnetism dynamics [1,2] and (ii) simultaneous structural and magnetism dynamics [3, 4,5].
