説明
In this study GdFeCo-multilayered structures are investigated by means of static magneto-optical measurements and time-resolved pump-probe spectroscopy. Fluence dependent time-resolved measurements demonstrate a complex behavior of the magnetization and the possibility of magnetization reversal. A method to distinguish contributions from different layers is proposed.
