Depth-resolved magnetization dynamics in Fe thin films after ultrafast laser excitation

We performed time-resolved x-ray resonant magnetic reflectivity measurements on a laser-excited ferromagnetic Fe thin film to simultaneously probe the transient magnetic and structural depth profiles with nanometer spatial and femtosecond temporal resolution. Our results show tha...

Transient Laser‐Induced Periodic Surface Structures Revealed by Time‐Resolved EUV Diffuse Scattering

ABSTRACT The formation of permanent laser‐induced periodic surface structures (LIPSS) on solid surfaces under impulsive laser irradiation above the damage threshold has been the subject of extensive research. Here, we report the formation of transient quasi‐periodic surface modul...
