摘要：
The surface magnetization dynamics at the nanosecond time scale is measured via spin polarization of the total electron yield obtained from synchrotron radiation pulses in 100kV Mott scattering experiments. Different reversal dynamics are observed for surface and bulk in an amorphous soft-ferro magnetic ribbon. indicating a weak coupling of the surface in the ns-lt range. Measurements vs. pulse duration of the reversal field reveal the presence of spring coupling behaviour if the Surface is well or poorly exchange-coupled to the bulk. (C) 2001 Elsevier Science B.V.
