  Abstract Perovskites LnV 0.5 Fe 0.5 O 3 (Ln = Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho and Er) were synthesized by rapid solidification from arc-melted samples and characterized by the study of their crystal structure and hyperfine properties. These metastable solid solutions crystallized in the Pbnm symmetry, with the iron and vanadium cations randomly distributed in the transition metal octahedral

  摘要 钙钛矿 LnV 0.5 Fe 0.5 O 3 (Ln = Y、La、Ce、Pr、Nd、Sm、Eu、Gd、Tb、Dy、Ho 和 Er) 是通过电弧熔化样品快速凝固合成的，并通过研究表征它们的晶体结构和超精细特性。这些亚稳态固溶体以 Pbnm 对称性结晶，铁和钒阳离子随机分布在过渡金属八面体位置。根据存在于钙钛矿 A 位点的镧系元素，铁以两种价态存在（即 Fe 3+ 和 Fe 2+ ）。随着钙钛矿接近其理想结构，这些钙钛矿的晶胞体积随镧系元素离子半径线性增加。在室温下，三价顺磁性 Mossbauer 组件的四极分裂用作 Goldshmidt 容差因子的间接测量。

  The reaction of rare-earth sesquioxides (Ln2O3 with vanadium dioxide (VO2) at 1400 °C and 50 kbar and 30 kbar was studied. Quadrivalent vanadium ions were reduced to the trivalent state, rare-earth vanadates(III) (LnVO3) being obtained. For LnVO3 a typical transformation of the ABO3-type compounds, one from the aragonite-type to the perovskite-type via the vaterite- or calcite-type structure was observed

  Single-crystalline tetragonal LnVO(4) (Ln - La, Nd, Sm, Eu, Dy) nanorods were prepared via a simple hydrothermal method, in the absence of any surfactant or template using cheap and simple inorganic salts as raw materials. The products were characterized by XRD. TEM, HRTEM, and PL. It has been shown that after the hydrothermal process, LaVO4 transformed its crystal structure from monoclinic to tetragonal phase, but LnVO(4) (Ln - Nd, Sm, Eu, Dy) have not exhibited the structural change. This could be associated with the change of lanthanide ion radius. TEM and HRTEM results show that the nanorods are pure, structurally uniform, single crystalline, and most of them are free from dislocations. Further study reveals the nanorods grow along the [001] direction. A possible growth mechanism of lanthanide orthovanadate nanorods was also proposed. The advantages of our method for the nanorods synthesis lie in the high yield and the low temperature and mild reaction conditions, which permit large scale production at low cost.

  The magnetic susceptibility chi and magnetization M were measured for SmVO3 and EuVO3. The antiferromagnetic transition was observed at T(t) = 132K for SmVO3, and the canting-antiferromagnetic transition occurred at T(t) = 123K in EuVO3. As for the SmVO3, , it was known that both of the Sm3+ and V3+ contribute independently to the paramagnetism above T(t), and only the V3+-spins order antiferromagnetically below T(t). While, in EuVO3, the magnetic moments of Eu3+ are dominant and V3+ is nonmagnetic above T(t), and the V3+-spins suddenly appear and come into the canting-antiferromagnetic state just below T(t).
