چکیده
To study the dependence of properties ternary oxides (Mn,Fe,Ga)2O3 with bixbyite structure on composition, temperature dependences magnetization and ac magnetic susceptibility two single-crystal samples different compositions obtained using flux method were analyzed. A detailed was carried out X-ray diffraction analysis, changes in structural parameters depending composition The dc Fe1.1Mn0.76Ga0.14O3 Fe0.65Mn1.1Ga0.26O3 bixbyites have been studied. Despite qualitatively similar behavior properties, significant differences also found, despite a small difference Mn/Fe/Ga ratio under study. It is shown that both compounds experience successive low-temperature phase transitions from paramagnetic at T = 20–32 K as lowered. Calculations Mydosh parameter for detected showed degrees ordering

Synthesis and Characterization of Tb[N(CN)<sub>2</sub>]<sub>3</sub>·2H<sub>2</sub>O and Eu[N(CN)<sub>2</sub>]<sub>3</sub>·2H<sub>2</sub>O: Two New Luminescent Rare-Earth Dicyanamides
Two new rare-earth dicyanamides, namely, Tb[N(CN)2]3‚2H2O and Eu[N(CN)2]3‚2H2O, have been prepared by ion exchange in aqueous solution, followed by evaporation of the solvent at room temperature. The structures of both compounds have been solved and refined from single-crystal and powder X-ray diffraction data, respectively. The two compounds are isostructural and are built up from irregular qu...

We have monitored the phase transformation from a Sandia octahedral molecular sieve Na2Nb2O6−H2O to a piezoelectric NaNbO3 nanowire through in situ X-ray diffraction (XRD) and transmission electron microscopy (TEM) measurements at high temperatures. After dehydration at 288 °C, the Na2Nb2O6−H2O becomes significantly destabilized and transforms into NaNbO3 with the increase of time. The phase tr...
