Abstract
We present an experimental analysis of domain wall fine structure at the surface of a semi-infinite ferromagnetic single crystal. It is found on Fe(100) that the domain walls in the surface show a Néel-like structure. This means that at the surface the rotation of the magnetization vector from one domain to the other occurs only within the surface. This is at variance with the commonly believed wall behaviour. For the 180°-walls we find a surface wall width of 220 nm ± 15 nm, while the value for the 90°-wall is 150 nm ± 30 nm.
