Cobalt-57-doped Fe, Co, and Ni sheets were studied by Mössbauer spectroscopy. The spectra indicated that the preferred direction of the effective magnetic field in Fe and Ni was parallel to the surface. With Co only little preference was observed. The observations are quantitatively explained by assuming that the closure domains may only show parallel to the local easy direction of magnetization, but otherwise tend to be as perpendicular to the normal vector of the surface as possible.
