摘要: Abstract We report here a size dependence of the coercive field in millimeter–centimeter range length scale 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 demagnetization factor.
