    Anomalous states of the structure of [Rb0.7(NH4)0.3]2SO4 crystals in the temperature range 4.2–300 K

    Crystals of [Rb0.7(NH4)0.3]2SO4 solid solutions are studied using x-ray diffractometry in the temperature range 4.2–300 K. No anomalies are revealed in the temperature dependences of the lattice parameters and th...

    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...
