Dynamique ultrarapide de l'aimantation dans les alliages de métaux de transitions et de terres rares
Abstract : My PhD work describes the pico and femtosecond magnetization dynamics using the time structure of X-rays. I studied the ultrafast demagnetization of thin films (~ 20 nm) for various transitions metals (TM) - rare earths (RE) alloys. My studies have been performed by using two experimental techniques which are sensitive to the magnetization and which are time resolved: tr-XMCD and tr-MCDAD. These two experimental techniques also show chemical selectivity allowing to distinguish the TM and RE dynamics. They are both based on pump-probe experiments which were used at the SOLEIL and BESSY II synchrotrons.
