Probing oxygen ordering in YBCO byin situ high temperature resistivity and X-ray diffraction studies

In Situ Thin Film Crystallization Studies Using High Temperature Grazing Incidence X-ray Diffraction (htgixrd)

We describe the experimental procedure and use of high-temperature X-ray diffraction techniques combined with grazing-incidence optics for in situ crystallization studies on several polycrystalline thin films; this technique is referred to as High-Temperature Grazing Incidence X-Ray Diffraction or (HTGIXRD). Temperature calibration techniques, sample positioning issues, and limitations of this ...

High-resolution High Energy X-ray Diffraction Studies of Charge Ordering in Cmr Manganites and Nickelates

High-resolution, high-energy, X-ray diffraction results are presented for the study of weak charge ordering phenomenon. By utilizing X-rays in the 100 keV region the dramatic increase in the penetration depth allows for both bulk-sensitive and highresolution measurements to be made. The strontium doped La2NiO4 system is a prototypical system in the understanding of strong electron-phonon coupli...

A Newly Developed High-temperature Chamber for in Situ X-ray Diffraction: Setup and Calibration Procedures

High Pressure-High Temperature, X-Ray Diffraction Apparatus

A tetrahedral-anvil press has been developed that permits x-ray diffraction powder measurements at pressures to 75 kb and temperatures to 1000°C. A counting technique, rather than photographic film, is used for x-ray detection. Sample tetrahedra of compressed LiH, boron, and boron-filled plastic are used in place of the pyrophyllite customarily used for this purpose. Two possible entrance pupil...
