Abstract

Neutron reflection and refraction in the glass/Fe(1000 angstroms)/Gd(50 angstroms) structure were investigated in the regime of generating a neutron standing wave. The polarized neutron beam-splitting method has been used. An external magnetic field, changing within the range 18 Oe to 4.4 kOe at room temperature, was applied in the plane of the film. Three sequentially occurring neutron spin transitions were discovered. Two of them were accompanied with a momentum transfer in the plane of the film, and the third was accompanied with a momentum transfer in the direction perpendicular to the plane. This can be explained by the existence of a domain structure where the magnetization vector is directed out of the film plane.
