摘要：
We report here a size dependence of the coercive field in the millimeter-centimeter range length scale of ribbon like samples prepared from ultra soft amorphous and nanocrystalline alloys. A model is proposed where surface pinned domain walls are considered having an effective stiffness constant linearly increasing with the demagnetization factor. (c) 2005 Elsevier B.V.
