Relations between the Thermodynamic Potentials for the Formation of Yttrium and Rare Earth Iron Perovskites and Garnets and the Ionic Radii of Yttrium and the Rare Earth Elements General formulas are derived for the Gibbs energies, enthalpies, entropies, and derived thermodynamic quantities related to the formation of yttrium and rare earth iron perovskites and garnets. Only the ionic radii of yttrium or the rare earth elements are required besides the temperature. 相似文献

Raman Spectra of the Rare Earth Orthovanadate The laser-Raman spectra of the tetragonal rare earth orthovanadates of the type LnVO4 (Ln = Pr to Lu) as well as those of ScVO4 and YVO4 has been recorded and interpreted with the aid of both, the site symmetry and the factor group analysis, using also IR data reported previously. The influence of the cations on the internal vibrations of the anion are discussed in detail. 相似文献
