The X-ray diffraction results of bulk targets indicate that with the decrease of the average ion radius , the structure transits from the rhombohedral to the orthorhombic phase. The magnetic properties show that there is a transition from the ferromagnetic to the paramagnetic state with the ...
The structure of the reaction products depended on the solution pH, mole ratios of BiO(NO3)0.5H2O to F, and the reaction time. We observed that BiO(NO3)0.5H2O is capable of removing 99% of the fluoride ions from the solution at pH 1-12 under optimal conditions. The ion exchange ...
Structure, transport and magnetic properties of electron-doped perovskites R(x)Ca(1-x)MnO(3) (R = La, Y and Ce). In this study, the transport and magnetic properties of electron-doped perovskites R(x)Ca(1-x)MnO(3) (R = La, Y and Ce) were investigated. As the R ion con... ...

The supplementary bonding results in a distortion of the nitrate ion. The three oxygen atoms that are bonded only to the 9-fold coordinated K atom have an average bond length of 1.20 vs the N O bond length of 1.24–1.29 for the oxygens bonded to the Er atom, both K atoms or both a...

The spectra show new bands that can be attributed to symmetry lowering of the complexed nitrate ion. Four possible structures are discussed for the complex, with Raman depolarization ratios favoring a complex with C2υ symmetry. A new Raman band at 335 cm−1 is assigned to the symmetric ...
The structure consists of polyhedral lead centers connected by doubly and triply bridging fluoride groups. We quantitatively exchanged the interlamellar nitrate groups of Pb3F5NO3 for dichromate, under ambient aqueous conditions. Nuclear magnetic resonance and UV−vis spectroscopy show the reaction ...
Antiferromagnetic Ba substituted SrMnO3 has a perovskite structure with a B-site magnetic ion which gives higher magnetic ordering temperatures. Ferroelectric transitions in these perovskites have been observed due to off centering of Mn4+ ions. In this work, we report synthesis of Sr1-xBaxMnO3 (...
