Abstract

Neutron standing waves in a layered magnetic structure were observed at total reflection by the registration of gamma-radiation from the gadolinium layer using time-of-flight method at a pulsed source of polarized neutrons. Using polarized neutrons, the ratio of gamma counts corresponding to the neutron beam polarization in the direction parallel to the magnetic field and in the opposite direction can be measured separately. The ratio of gamma counts measured at two polarization states of neutrons proves that over the surface of the Fe layer a neutron standing wave is formed.
