Néel-type surface magnetic wall structure is observed on thick samples such as 1.4-μm-thick Permalloy polycrystal film and 1-μm-thick Co-based amorphous films. The structure is observed by using spin-polarized scanning electron microscopy. These observations are consistent with Hubert’s two-dimensional domain wall model for thick films [Z. Angew. Phys. 32, 58 (1971)].
