Probing magnetic domain wall proﬁles by neutron spin precession

P. Thibaudeau, F. Ott, A. Thiaville, V. Dubuget and F. Duverger

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 *lm with in-plane crossed anisotropies.
