Probing of Spin Wave Resonances in in (Ga,Mn)As by Time-Resolved Magneto-Optical Technique

Abstrakt

We report on all-optical detection of magnetization dynamics in the ferromagnetic semiconductor (Ga,Mn)As in the presence of spin-wave resonances (SWRs) using a time-resolved magneto-optical (TRMO) technique.
