Abstract

Light-induced precession of ferromagnetically-coupled Mn spins is studied systematically in the pico- to sub-nano-second time regime through time-resolved magneto-optical signals collected by one-color, pump-and-probe experiments. Induced precession is discussed in terms of a relative change in magnetic anisotropy originated at least in part by the non-thermal process. (© 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
