Creator:: Laurita, Geneva, Vielma, Jason, Winter, Florian, Berthelot, Romain, Largeteau, Alain, Pöttgen, Rainer, Schneider, G., and Subramanian, M. A.
Abstract:: A complete solid solution between the anion-deficient pyrochlore Ag₂Sb₂O₆ and the ideal pyrochlore Cd₂Sb₂O₇ has been synthesized through the standard solid state ceramic method. Each composition has been characterized by various different techniques, including powder X-ray diffraction, optical spectroscopy, electron paramagnetic resonance and ¹²¹Sb Mössbauer spectroscopy. Computational methods based on...

Creator:: Li, Jun, Sinith, Andrew E., Jiang, Peng, Stalick, Judith K., Sleight, Arthur W., and Subramanian, M. A.
Abstract:: The discovery of a brilliant-blue color upon the introduction of Mn³⁺ to the trigonal-bipyramidal (TBP) sites in YInO₃ has led to a search for other hosts for Mn³⁺ in TBP coordination. An obvious choice would be YAlO₃. This compound, which has only been prepared through a citrate precursor route, has...

Abstract:: The solid solutions of chlorapatite compounds Ba₅Mn₃−[subscript]xV[subscript]xO₁₂Cl (x = 0–3.0) and Ba₅Mn₃−[subscript]xP[subscript]xO₁₂Cl (x = 0–3.0) have been synthesized through solid state reactions and Pechini or sol–gel method using citric acid. The colors of the samples change from white (x = 3.0) through turquoise (x = 1.5) to dark green (x...

Creator:: Schmidt, Whitney, Berthelot, Romain, Etienne, Laetitia, Wattiaux, Alain, and Subramanian, M. A.
Abstract:: A new compound Na3LiFeSbO6 has been synthesized by conventional solid state methods and investigated using X-ray diffraction, DC magnetic susceptibility, 57Fe Mössbauer spectroscopy and optical measurements. This compound crystallizes in a monoclinic unit cell and is related to a family of honeycomb ordered layered oxide materials where Na+ fills octahedral...

Creator:: Matar, S. F., Subramanian, M. A., and Etourneau, J.
Abstract:: From DFT based calculations establishing energy-volume equations of state, a proposition of high pressure candidate structures with reduced volumes, namely columbite and trirutile are proposed for fordite mineral SnNb₂O₆. The key effect is the destabilization of divalent tin in fordite towards tetravalent state upon compression. This is helped with smaller...

Creator:: Grajczyk, Rosa, Chan, Adam, Ramirez, A. P., and Subramanian, M. A.
Abstract:: The solid solution of In₂Fe₂₋ₓGaₓCuO₇ (space group P6₃/mmc) was synthesized and investigated through X-ray diffraction and magnetic susceptibility studies. Limited changes to the lattice parameters were observed as a result of the similar ionic radii for Fe³⁺ and Ga³⁺ in the trigonal bipyramidal (TBP) crystallographic site. An increase in the...
