ABSTRACT
In this paper, we give a direct experimental evidence of the long hypothesized phase separation scenario in strongly correlated manganite-based systems. High resolution, high-pressure synchrotron x-ray diffraction measurements on La1.4Sr1.6Mn2O7 as a function of temperature reveal the instability with P of the ferromagnetic phase leading, above a threshold P, to a phase separation between two phases with different orbital occupancies.

    We present novel time- and angle-resolved x-ray diffraction (TARXD) capable of probing structural and chemical evolutions during rapidly propagating exothermic intermetallic reactions between Ni-Al multilayers. The system utilizes monochromatic synchrotron x-rays and a two-dimensional (2D) pixel...

    Diamonds are not only important for jewelry, but also have a variety of industrial applications. The presence of defects can often produce desirable properties in diamond. For example, plastic deformation may cause diamonds to appear pink or red. In addition to spectroscopic methods and...

    The texture of CoSi2 films on Si(001) substrates has been examined using synchrotron based high-resolution pole figure analysis. We find that axiotaxy, a recently recognized type of texture which was observed in NiSi thin films on Si(001), is also occurring in CoSi2 layers. Typical of axiotaxy...

    Bulk regular domain structures created in a LiNbO3 crystal by aftergrowth thermoelectrical treatment technique were studied by high-resolution x-ray diffraction and topography. Topographic contrast can be observed between neighboring domains and is related to the difference in the direction of...
