An experimental method is presented which allows to probe the shape of a magnetic domain wall. The method is based on the precession of the spin of neutrons traveling across the domain wall structure. This technique is experimentally demonstrated on a planar (half) Bloch wall created within the thickness of a soft magnetic film with in-plane crossed anisotropies.
