综述了高磁导率材料（晶态镍铁片、非晶和纳米晶薄带）的磁微结构。对于大多数这样的“极端”的软磁铁可识别的域和墙被发现由于残余各向异性。只有在各向异性消失的情况下，传统的域被替换为一个平稳变化的磁化首次证明在高品质坡莫合金片和适当处理的非晶带。
The magnetic microstructure of high-permeability materials (crystalline NiFe-sheets, amorphous and nanocrystalline ribbons) is reviewed. For the majority of such ‘extreme’ soft magnets identifiable domains and walls are found due to residual anisotropies. Only in cases of vanishing anisotropy conventional domains are replaced by a smoothly varying magnetization as demonstrated for the first time in high-quality Permalloy sheets and properly treated amorphous ribbons.
