Magnetization reversal in a-GdTbFe investigated by time-resolved, spin-polarized photoemission

Abstract Pulsed laser induced, spin-polarized photoemission reveals that the magnetization reversal in a-GdTbFe films occurs in less than 1 ns if the sample is held below the compensation temperature (Tcomp). Above Tcomp the magnetization reversal time exceeds 16 ns.
