Аннотация: High-temperature G0 polymorph of Rb2KMoO3F3 has been prepared by melt solidification. Micromorphology and chemical properties of the final product were evaluated by scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). The elpasolite-related crystal structure of G0-Rb2KMoO3F3 has been refined by Rietveld method at T = 298 K (space group Fm-3m, a = 8.92446(8) Å, V = 710.76(1) Å3; RB = 3.55%). Ferroelectric G1-Rb2KMoO3F3 polymorph, earlier reported at T˂328 K, is not found at T = 298 K.

Аннотация: The magnetization of cation-substituted CoxMn(1-x)S sulfides upon cooling in zero magnetic field and in a field in the temperature range 4-300 K has been measured and the resistance versus magnetic field (up to 10 kOe) dependences have been obtained. Magnetoresistance and temperature hysteresis of magnetization versus prehistory are found at the magnetic field H < 0.1 T and at T < 240 K. The interrelation between the magnetic and elastic subsystems of the CoxMn1-xS solid solutions has been established. A jump in the coefficient of thermal expansion is observed at the Neel temperature. The features of the physical properties are explained by orbital ordering. (C) 2010 Elsevier Ltd.

Аннотация: The structural, magnetic, electrical, and thermoelectric properties of GdXMn1-XS (0.01 <= X <= 0.3) solid solutions synthesized for the first time on the basis of alpha-MnS have been studied experimentally in the temperature range 77-1000 K in magnetic fields up to 10 kOe. The synthesized samples are antiferromagnetic semiconductors with an NaCl-type cubic lattice typical of a-MnS. Both concentration (X-c = 0.3) and temperature (T-c = 450 K) metal-insulator phase transitions have been observed. The concentration metal-insulator transition is accompanied by a decrease in resistivity and thermopower by twelve and two orders of magnitude, respectively, with the change in conductivity from p-type to n-type.

Аннотация: Relaxation oscillations of the crystallization front in a gradient temperature field have been observed for water adsorbed on a metal film deposited on a glass substrate. The metal film plays an important role in heat removal from the crystallization front and determines the existence of oscillations. A possible mechanism is proposed for the development of oscillations. It is shown that the oscillations observed are similar to the oscillations of the front of self-propagating high-temperature synthesis. (C) 2000 MAIK "Nauka / Interperiodica".
