Hydrogen Absorption in Metal Thin Films and Heterostructures Investigated in Situ with Neutron and X-ray Scattering
Due to hydrogen possessing a relatively large neutron scattering length, hydrogen absorption and desorption behaviors in metal thin films can straightforwardly be investigated by neutron reflectometry. However, to further elucidate the chemical structure of the hydrogen absorbing materials, complementary techniques such as high resolution X-ray reflectometry and diffraction remain important too...
متن کاملPinpointing 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...
متن کاملNeutron scattering—The key characterization tool for nanostructured magnetic materials
The novel properties of materials produced using nanoscale manufacturing processes often arise from interactions across interfaces between dissimilar materials. Thus, to characterize the structure and magnetism of nanoscale materials demands tools with interface specificity. Neutron scattering has long been known to provide unique and quantitative information about nuclear and magnetic structur...
متن کاملDetermination 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...
متن کاملDetection of Multilayer Nano Structures by One Directional Polarization Analysis in Neutron Reflectometry
Submitted: Jul 16, 2013; Accepted: Aug 25, 2013; Published: Aug 29, 2013 Abstract: Due to the sensibility of neutron spin to the intrinsic magnetic field of magnetic materials, polarized neutron reflectometry is widely used in investigation of magnetic properties of nano-structures. Type and thickness of a multilayer can precisely be determined by measuring the polarization of reflected neutron...
