Doping of impurities may affect the Curie temperature (T$\sb{\rm c})$ associated with the ferroelectric phase transition in terms of lattice harmonicity and anharmonicity including the creation of the defect energy. Its ...

Thermal diffuse scattering measurements were performed at several temperatures. A [011] transverse optic soft mode was determined to exist. The temperature dependence of this phonon mode was carefully studied as the ...

Analysis of thermal diffuse scattering of x-rays (TDS) has recently shown great promise as a tool for phonon studies, complementing more traditional neutron scattering techniques. Quasi-elastic x-ray scattering from thermally ...

Two different aspects of the charge-density-wave (CDW) state were studied in the quasi-onedimensional metal blue bronze (Ko.3oMo03). In the primary experiment reported in this thesis, pinning of the CDW phase by lattice ...

We have studied the phase transition at the (111) surface of Cu3Au by glancing incidence x-ray scattering. The experiment was designed to approach the general question of surface behavior near a bulk first order phase ...

An experimental study of the deformation at a notch under tensile loading and by hydride precipitation has been conducted with x-ray diffraction topography. Lang topography, asymmetric crystal topography (ACT) and synchrotron ...

The results of an investigation of the production of g- hyperons in K-p interactions at 5.5 BeV/c are presented. The data were obtained from a 400,000 picture exposure of the MURA 30’’ hydrogen bubble chamber at the Argonne ...
