Multiscale local ordering in the prototypical uniaxial relaxor SrBaNbO single crystal at room temperature.

The structure and diffuse scattering in uniaxial relaxor SrBaNbO single crystal have been studied by x-ray diffraction at room temperature. Two different kinds of local ordering with different correlation lengths and different shapes of correlation functions have been revealed. The values of correlation lengths have been determined from analysis of experimental data.

SEM and AFM Studies of Two-Phase Magnetic Alkali Borosilicate Glasses.

The morphology and composition of four types of two-phase alkali borosilicate glasses with magnetic atoms prepared by inductive melting have been studied. The results of scanning electron microscopy point to uniform distribution of Na, Si, and O atoms in these samples while magnetic iron atoms form ball-shaped agglomerates. The magnetic properties of these agglomerates have been confirmed by magnetic force microscopy.

Morphology and magnetic properties of ferriferous two-phase sodium borosilicate glasses.

This contribution is devoted to the study of morphology and magnetic properties of sodium borosilicate glasses with different concentrations (15, 20, and 25 wt.%) of α-Fe2O3 in an initial furnace charge. These glasses were prepared by a melt-quenching method.

Structure and properties of confined sodium nitrite.

The temperature evolution of the structure of NaNO(2) nanocomposite ferroelectric material in a porous glass with 7 nm pores was studied by neutron diffraction in temperature region from room temperature up to the melting, i.e. in the ferro- and paraelectric phases.

Temperature evolution of sodium nitrite structure in a restricted geometry.

The NaNO2 nanocomposite ferroelectric material in porous glass was studied by neutron diffraction. For the first time, the details of the crystal structure including positions and anisotropic thermal parameters were determined for the solid material, embedded in a porous matrix, in ferro- and paraelectric phases. It is demonstrated that in the ferroelectric phase the structure is consistent with bulk data, but above transition temperature the giant growth of amplitudes of thermal vibrations is observed, resulting in the formation of a "premelted state.
