Bragg diffraction at grazing incidence of neutrons from a magnetic film decomposed into a set of ferromagnetic domains is considered within the frame of the distorted wave Born approximation. It is shown that the diffracted intensity measured as a fu

For the design of multicompositional materials with a spatially defined order of different components symmetric polystyrene(deuterated)-block-polybuthyl methacrylate P(Sd-b-BMA) lamellar thin films are used as a structure-directing matrix for the nan

Grazing incidence nuclear multilayer diffraction of synchrotron radiation from a periodic stack of alternating 56Fe and 57Fe layers was observed. Resonant layer fraction, substrate size, flatness, and surface roughness limits were optimized by previo

The isotopic ordering of H2−D2 mixtures adsorbed at low temperature on graphite in the monolayer range is measured by small angle neutron scattering (SANS). We show that below 8 K, solid mixtures exhibit isotopic clustering at large density (monola

A polarized neutron scattering investigation of the flux line lattice in the type-II superconductor niobium is reported. A modulation of the nuclear lattice has been detected, and the magnitude of the first Fourier component of the lattice distortion

We discuss an approach towards understanding the limitations of X-ray or neutron reflectivity methods for the determination of an interfacial density profile. A novel analysis is presented based on an expansion of the reflectivity function in terms o

The capabilities of the method of using unpolarized neutron off-specular scattering for investigation of magnetic structures in exchange-coupled magnetic multilayers are thoroughly examined. It is demonstrated that strong anomalies in spin-flip selec

We studied the H vibrations in H-doped YBa2Cu3OxHy, (y=0.6) by neutron spectroscopy. Neutron spectra were taken at 10 and 14 K from both orthorhombic (x approximately=6.9) and tetragonal (x approximately=6.3) samples. The spectra exhibit large H-indu

Polarized neutron specular reflection (PNSR) was used for the study of the magnetization profile of the sandwich Pd/Co(21 A/Pd in a saturating magnetic field prepared by high vacuum vapor deposition on a Au film deposited on a Si(111) and Si(100) sub
