摘要：

We present a study of quasi-static and dynamic hysteresis properties in rapidly-quenched 6.5 wt% SiFe ribbons, in the as-cast state and after various annealing treatments. Data are interpreted by static and dynamic Preisach models. The modifications of static loop shapes vs. grain size as well as those of dynamic loop shapes vs. magnetizing frequency are well described by a lorentzian Preisach distribution. Comparison between experiments and model predictions provides an estimate for the size of the correlation regions responsible for dynamic magnetization changes. This size is found to be about one half of the average grain size in samples annealed at 1100 degrees C for 1 hour.
