Topical Review of Quantum Materials and Heterostructures Studied by Polarized Neutron Reflectometry

Polarized Neutron Reflectometry of Nickel Corrosion Inhibitors.

Polarized neutron reflectometry has been used to investigate the detailed adsorption behavior and corrosion inhibition mechanism of two surfactants on a nickel surface under acidic conditions. Both the corrosion of the nickel surface and the structure of the adsorbed surfactant layer could be monitored in situ by the use of different solvent contrasts. Layer thicknesses and roughnesses were eva...

Application of polarized neutron reflectometry to studies of artificially structured magnetic materials

Pinpointing chiral structures with front-back polarized neutron reflectometry.

A new development in spin-polarized neutron reflectometry enables us to more fully characterize the nucleation and growth of buried domain walls in layered magnetic materials. We applied this technique to a thin-film exchange-spring magnet. After first measuring the reflectivity with the neutrons striking the front, we measure with the neutrons striking the back. Simultaneous fits are sensitive...

A review on neutron shielding performance of nano-composite materials

Neutron sources employed in different applications in both medicine and industry. Due to the harmful effects of neutron particles on living organisms, radiation shields have played a vital role in radiation protection against neutrons. In recent decade, numerous investigations conducted on the design and fabrication of nanocomposites as more efficient shielding materials against fast and therma...

Determination of the magnetic field penetration depth in YBa2Cu307-d superconducting films by polarized neutron reflectometry

Polarized neutron reflectometry was used for the direct measurement of the magnetic-field penetration depth in a high-temperature (HT,) superconducting film. Two scattering geometries were used. The deduced neutron scattering length density profile gave an exact picture of the composition of the film. The fit to the spin-asymmetry yielded a magnetic-penetration depth of 1400 2 100 A at a temper...
