Short range order (SRO) in Al Zn ( c = 7 and 17at%) single crystals has been measured by the neutron diffuse scattering technique at temperatures above the miscibility gap. The Warren-Cowley short range order parameters have been obtained by least-sq

The quasielastic (QES) and the inelastic scattering (INS) observed in the neutron scattering spectra of polycrystalline Na 3 Cr 2 P 3 O 12 (noted NaCr) from 0.8 to 673 K is due to spin fluctuations. The QES of NaCr and NaFe were analyzed within de Ge

The influence of magnetism on atomic short range order is shown in a single crystalline FeAl{sub 19.5} at % alloy in the disordered phase. The short range order has been measured in the paramagnetic state between 973 and 1 573 K on D7 at ILL through

Polarized neutrons and polarization analysis were used to determine the total amplitude of magnetic fluctuations in tetragonal YBa2Cu3O6+δ for energies below 30 meV, both in the magnetically ordered state below and in the paramagnetic state above th

We present an approach to obtaining a modular hard x-ray Wolter-I type telescope based on combining present replication technologies, for complete sub-arc minute cylindrical shells, with deposition of Ni/C broad-band hard x-ray multilayers. Based on

A beam of thermal neutrons traversing a Bloch wall is partly refracted. The intensity distribution on refracted and direct beams depends on the wall thickness. A comparison of the calculated intensities with the measured ones gives the wall thickness

Neutron polarisation analysis techniques have been used to extract the magnetic contributions to the total neutron scattering cross sections of a well characterized superconducting sample of YBa2(Cu0.9Fe0.1)3O7.2. Paramagnetic-like scattering is seen

The rotation, φ PNC , of a neutron beam polarization vector due to parity non-conserving forces is observed in natural Pb and Sn targets. The following values for φ PNC / l in units of 10 −6 rad/cm are found: Pb: +(2.24 ± 0.33), and Sn: −(3.19

For the first time, neutrons have been critically reflected from a soap film. In addition, interference fringes were also measured from whose spacing the thickness of the film could be determined. Because the film solution consisted of hydrogeneous s
