1Phase Behavior and Crystal Structure of Perovskite-Type Rare Earth Complex Oxides显示文摘Several compounds of rare earth complex oxides containing manganese and titanium were synthesized in Ar, and their crystal structures were analyzed by powder X-ray diffraction data and Rietveld method. Structures of A 0.67 Ln 0.33 Mn 0.33 Ti 0.67 O3 (A=Ca or Sr and Ln=rare earth) were found to have orthorhombic symmetry with the space group Pnma, and their interatomic distances and bond angles were obtained. This space group was also derived from electron microscopic study. Electrical conductivity of Ca 0.67 Ln 0.33 Mn 0.33 Ti 0.67 O3 for several rare earth elements showed a semiconducting property with the activation energy of 0.4 eV. Some of these compounds of the strontium system show the antiferromagnetic properties below 10 K.Migaku Kobayashi Ryoko Katsuraya Tsubasa Nara Yusuke Tomita Hiromi Nakano Naoki Kamegashira 2006Journal of Rare Earths2006,24,6:7

20Stability of phases in (Ba, Gd)MnO_3 solid solution system显示文摘The existing phases in BaxGd1-xMnO3 solid solution system (0≦x≦1) were studied by analyzing the detailed crystal structure of each composition from the results of the Rietveld method using powder X-ray diffraction data. For a small substitution of Ba for Gd (0≦x<0.1), the orthorhombic phase with a perovskite type structure (Pnma space group) was stably formed and this fact was supported by the electron diffraction data. There existed an intermediate phase of Ba0.33Gd0.67MnO3, which was characterized as the tetragonal phase with perovskite structure. The composition range of this phase was narrow and almost line compound. Between the regions of these phases, there ex- isted two-phase region. There was also a two-phase region between the intermediate tetragonal phase and BaMnO3. Measurement of electrical conductivities of these orthorhombic solid solutions and tetragonal phases showed semiconducting behaviors for both phases and the existence of the phase transition at high temperature for the orthorhombic phase. The transition temperature decreased as the Ba content increased.Migaku Kobayashi Hidenori Tamura Hiromi Nakano Hirohisa Satoh Naoki Kamegashira 2008Journal of Rare Earths2008,26,2:0
