Polarized beam experiments using synchrotron sources provide a direct measurement of both the orbital- and the spin-angular momentum densities. Similar information can be obtained by applying sum rules for the integral of the imaginary part of the fo

We carried out a diffraction profile shape of a study of a nearly perfect superconducting single crystal of the (Nd 1.85 Ce 0.15 )CuO 4 compound in order to detect cooperative deformations associated to the superconducting transition, and check the e

NbnAlm multilayer films grown on oxidized Si(100) at room temperature by magnetron sputtering have Nb[110] and A[111] texture. The films have ∼1% coherency strains which decrease with increasing modulation wavelength. The composition modulation is

The question of coherent interfaces between multilayers of sputtered Nb and Cu is addressed using x-ray scattering. It is found that the interfaces are not coherent and the NbCu multilayers are composed of columns strongly layered along the growth di

Acoustic-phonon dispersion relations of black phosphorus in its orthorhombic $A11$ phase have been measured along three principal directions mainly at 1 bar and 15.4 kbar. An anomalous softening has been observed on the LA[100] branch whose vibration

Various possibilities offered by X-ray diffraction measurements from ferromagnetic materials are discussed and experimental studies are reviewed. Recent investigations have been performed with synchrotron X-ray beams which can be tailored to the expe

A new family of rare earth-rhodium-tin intermetallic compounds, with the representative formula (RE)Rh x Sn y , has been synthesized in single crystal form. The compounds containing the heavier rare earths are superconducting and those with the light

The structure of the lithium inserted rutile-based compound LiMoO2 has been determined from neutron powder diffraction data by use of the Rietveld profile technique. The inserted Li is incorporated into the MoO2 lattice in octahedral sites with an av
