    was found that solid solutionsLn1−xNdxTiO3(Ln=Ce and Pr) with an orthorhombic perovskite structure exhibited a characteristic suspectibility peak phenomenon in their susceptibility–temperature (χ–T) curves, similar to that for La1−xSmxTiO3reported previously. However, it was observed only in a region in whichxwas higher (0.5≤x) than in the latter system (0

    A series of perovskite Nd1-xAxTiO3 (A = Ca, Sr, Ba) compounds has been prepared by the dc-arc melting technique in the composition range 0x ≤ ∼1.0. The substitution of Sr and Ba in NdTiO3 results in structural phase transitions from orthorhombic (Pbnm) to cubic (Pm3m). The Nd1-xCaxTiO3 series remains orthorhombic throughout the range studied.

    作者:K. Yoshii

    日期:2000.2
    The A-site-deficient perovskite compounds Ln2/3TiO3 with Ln=Pr and Nd were synthesized under an H2–Ar atmosphere at 1400 and 1450°C, respectively. The samples were found to have slight oxygen deficiencies of δ∼0.006 in Ln2/3TiO3–δ. It was also found that no single-phase compound could be prepared in air from the same initial mixtures. Their crystal structures were assigned to a double perovskite structure

    Electrical resistivities were measured as a function of temperature in the range below 300 K for single-crystal samples of PrTiO3 and NdTiO3. Both materials are semiconductors with room temperature activation energies of 0.03 to 0.04 eV. Magnetic susceptibilities for PrTiO3 and NdTiO3 follow the Curie-Weiss law at high temperatures with Cm = 1.73(3) and Θc = −49(3) K (PrTiO3), and Cm = 1.77(3), Θc
