    3D-incommensurate composite structures in (Rbx(NH4)(1 − x))2SO4 crystals

    Detailed structural studies of (Rbx(NH4)(1 − x))2SO4 solid solutions have been performed. It is shown that the crystals consist of incommensurate composite phases. The newly discovered composite structures differ...

    Structural hierarchy and transformations in crystals of the perovskite family

    The specific features of structural transformations in lanthanum manganite and lithium niobate are analyzed in terms of the macrosymmetry conservation principle discussed in the papers by L.A. Shuvalov. The po...

    Structural aspects of solid-state amorphization in GaSb single crystals

    As is well known, the GaSb I phase that is stable at room temperature is transformed under high pressures and temperatures into the GaSb II phase, which, being frozen in liquid nitrogen, becomes a metastable p...

    X-ray diffraction in polydomain crystals modulated by transverse waves of atomic displacements. 2. Two-wave modulation of crystals

    X-ray diffraction in an orthorhombic crystal modulated by two transverse-displacement waves propagating along one of the crystallographic directions has been numerically studied within the framework of the kin...

    X-ray diffraction by polydomain crystals modulated by transverse waves of atomic displacements. 1. Single-wave modulation in crystals

    The intensity distributions of diffuse X-ray scattering caused by domains characterized by the transverse wave of atomic displacements polarized in the (010) plane and propagating along the [001] direction are...

    Twins, and Structure of Twin Boundaries

    The twinning parameters for crystals of the RBa2Cu3O7 system, R being a rare-earth element (Y, Gd, Eii, Ho), and the La2CuO4 system were determined by X-ray methods. It appeared that twin boundaries in a l-2-3-O7
