Phase-targeted X-ray diffraction

A powder X-ray diffraction (XRD) method to enhance the signal of a specific crystalline phase within a mixture is presented for the first time. Specificity to the targeted phase relies on finding coincidences in the ratios of crystal d spacings and the ratios of elemental characteristic X-ray energies. Such coincidences can be exploited so that the two crystal planes diffract through the same s...

Oxides: neutron and synchrotron X-ray diffraction studies

We shall review some results from several areas of oxide science in which neutron scattering and X-ray synchrotron scattering exercise a complementary role to high-resolution transmission electron microscopy. The very highresolution time-of-flight neutron diffraction technique and its role in studies of the magnetic structure of oxides will especially be reviewed. The selected topics of structu...

X-Ray and Neutron Diffraction with Amorphous Ti

The amorphous alloys Ti 6 7 Si 3 3 , V 6 7Si 3 3 , and Cr , 7 Si 3 3 were produced by sputtering. Their structure was investigated by X-ray and neutron diffraction. X-ray diffraction showed that the structure of the three metallic glasses is not isomorphous. Neutron diffraction showed that S i -S i atomic pairs occur preferentially with distances distinctly larger than the atomic diameter of th...

Glass Studied by Neutron and X-Ray Diffraction

The short-range order of K P 0 3 glass has been studied by diffraction methods in order to make evident the different behaviour of the P-O bonds within the P 0 4 tetrahedron. The oxygen sites are devided into bridging and terminal (non-bridging) oxygen sites, corresponding to two P 0 bond lengths, the difference of which amounts to 14.5 pm. Previous conclusions about the changes of the P 0 bond...

Soft X-ray resonant magnetic diffraction.

We have conducted the first soft x-ray diffraction experiments from a bulk single crystal, studying the bilayer manganite La2-2xSr1+2xMn2O7 with x=0.475 in which we were able to access the (002) Bragg reflection using soft x rays. The Bragg reflection displays a strong resonant enhancement at the L(III) and L(II) manganese absorption edges. We demonstrate that the resonant enhancement of the ma...
