We are developing new methods for studying the dynamics of complex magnetic materials in 3D and on ultrafast time scales. Utilizing lab-scale laser sources, we have recently built the compact beamline, which provides unique insight into the dynamics of magnetic moments of separate species within a composite system beyond the typical “single-projection” approach. With the new capabilities, we are investigating the prospects for magnetization reversal and the details of magnetization dynamics in technologically relevant ferromagnetic films with high anisotropy.
The lab is funded by the Director’s Fund of IJS and is co-financed by ARIS “Paket 19” and “Paket 21”.
