Neutron reflectometry allows retrieving structural and magnetic information about surfaces and interfaces. The incoming neutron beam at low incident angle is reflected from the surface or interface depending on the neutron scattering length density of the structure. Structures and interfaces up to several 100 nm thickness can be penetrated with a depth resolution even below 1 nm. Typical examples for neutron reflectometry are the proof of the magnetic structure of magnetic thin films, the detection of interdiffusion between neighbouring layers of different isotopes, the layer formation at surfaces and interfaces of liquids or in polymers or the adsorption of biomolecules at interfaces.
