Vibronic intensities in centrosymmetric coordination compounds of the rare earths Part II. A vibronic crystal field-closure-ligand polarisation model and applications to the PrCl3-6 and UBr2-6 complex ions in octahedral symmetry
(Elsevier, 1997)
A symmetry adapted formalism to evaluate the vibronic intensities induced by the ungerade vibrational modes in centrosymmetric coordination compounds of the rare earths is put forward and applied to several selected ...
New quaternary alkali metal, rare earth (3+) thiophosphate, K2SmP2S7 with both [P2S6]4 and [PS4]3 anions
(Elsevier, 2008)
A new quaternary alkali metal, rare earth thiophosphate was synthesized by the ceramic method and characterized by single crystal X-ray diffraction: K2SmP2S7 crystallizes in the monoclinic space group C2 (no. 5) with the ...
Mineralization potentials of pegmatites in the nasarawa area of central nigeria
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2008)
Pegmatites in Nasarawa area of Central Nigeria lie within a fracture-controlled east-north-east trending rare metal pegmatite belt closely associatedwith late PanAfrican peraluminous granites inNigeria. Trace elements of ...

Electron-phonon coupling in mixed-valence systems
(1991)
The electron-phonon interaction in mixed-valence systems is modeled on the basis of an Anderson-like Hamiltonian that describes a cluster of one metallic rare-earth cation surrounded by six anions. Coupling between the ...
Intra- and inter-network interactions in magnetic oxides
(ELSEVIER SCIENCE BV, 2006-10-01)
Partial substitutions of Mn by a transition metal Me in the rare-earth manganites REMexMn1-xO3 results in the simultaneous presence of Mn3+ and Mn4+, triggering double exchange ferromagnetic mechanisms. The RE sublattice ...
