FIELD: physics.
SUBSTANCE: reflection coefficient of a beam of polarised neutrons is measured. The test nanolayer is put inside a non-magnetic nanolayer with low value of neutron interaction potential, which in turn is put between two non-magnetic nanolayers with high neutron interaction potential. The entire structure of nanolayers is put on a substrate. From the relationship between four reflection coefficients of neutrons and the transmitted wave vector, corresponding to transition of neutrons from two initial states with projection of neutron spin along the direction of the magnetic field and opposite to two final states with the same spin projection, the spatial distribution of the magnetic moment is determined.
EFFECT: increased sensitivity of measuring spatial distribution of the magnetic moment vector in a nanolayer.
