Resonant neutron reflectometry

† 
Joint Institute for Nuclear Research, 6 Joliot-Curie Str., Dubna, Moscow Region, 141980, Russian Federation

The paper reports principles of a new technique based on neutron scattering—resonant neutron reflectometry. It utilizes the resonant amplification of the neutron wave field in quasi-2D layered systems. The practical implification of this approach significantly increases sensitivity in determining the parameters of structural and magnetic potentials, the position of magnetic layers, as well as the spatial distribution of isotopes in multilayered nanostructures. It can be considered as an effective technique complementary to the standard reflectometry.

Typically, an English full text is available in about 1 month from the date of publication of the original article.
