Prediction of Formability in Perovskite-Type Oxides~!2008-08-05~!2008-10-08~!2008-12-05~!

“…The 91 systems in the range (r B /r O is not less 0.414) cannot form cubic perovskite structure as seen in Table 1. According to Galasso's report [1] [31,32], rare earth perovskite oxides, have orthorhombic structure [3,34]. We have also found in Fig.…”

“…A large number of perovskite-type oxides have been studied because of their interesting properties, including superconductivity, insulator-metal transition, ionic conduction characteristics, dielectric properties and ferroelasticity [1][2][3]. Additionally, they have received great attention as high temperature proton conductors with the possibility of applications in fuel cells or hydrogen sensors.…”

“…Perovskite is one of the most frequently encountered structures in solid-state physics, and it accommodates most of the metallic ions in the periodic table with a significant number of different anions. During the last few years, many experimental and theoretical investigations were devoted to the study of perovskite solids: typically ABX 3 (A: large cation with different valence, B: transition metal and X: oxides and halides). These solids are currently gaining considerable importance in the field of electrical ceramics, refractories, geophysics, astrophysics, particle accelerators, fission, fusion reactors, heterogeneous catalysis etc [4][5][6][7].…”

Magnetic Properties of LnMnO3 (Ln=Ho, Er, Tm, Yb, and Lu)

“…Ca-substituted compounds Ln 0.5 Ca 0.5 MnO 3 , where the nominal valence of the Mn ions is 3.5+, were also prepared for comparison; their magnetic properties are briefly considered as well. Magnetic properties for such systems have been reported for Y 0.5 Ca 0.5 MnO 3 (11,12) and Y 0.7 Ca 0.3 MnO 3 (13), exhibiting charge order below 260 K and spin-glass behavior below 30 K, respectively.…”

Electronic and magnetic structure of carbides RRh3C

“…1 Introduction ABO 3 -type perovskites have been largely studied because of their interesting features, including superconducting transitions, insulating-metallic transitions, ion-conduction characteristics, dielectric properties, and ferroelasticity [1][2][3][4][5]. These crystals have received considerable attention both in theory [6][7][8][9] and experiment [10,11] since these materials have important applications in electro-optic, waveguides, laser frequency doubling, highcapacity computer cells, etc.…”
