Study of crystal structure and phase transition studies in perovskite-type oxides using powder-diffraction techniques and symmetry-mode analysis.
Orayech, Brahim (2015-07-15)In this work, six families of Perovskite materials have been studied: Na0.5K0.5NbO3, La2MMnO6, Sr2MSbO6 (M=Ln, Y, In), Ca2MSbO6 (M = Ln, Y, In) Sr2M1-xM¿xTeO6 (M, M¿= Co, Mn, Ni, Fe, Mg), and NaLnMM¿O6 (Ln = La, Nd, Pr; ...
