  稀土-Sn3 化合物磁性有序温度的压力依赖性

  摘要：

  摘要 对 PrSn3、GdSn3、GdSn3 和 CeIn3 的 Neel 温度 TN 的静水压力依赖性测量进行了报道。发现 PrSn3 和 NdSn3 的 TN 随施加的压力而增加，而 TN 在 GdSn3 和 CeIn3 的实验误差内与压力无关。发现略微缺乏 Sn 的 RESn3（RE=稀土）化合物始终具有弱铁磁性。RESn3 化合物的物理性质与稀释的超导 (La RE)Sn3 合金的相应性质类似。PrSn3 和 CeIn3 的高压数据与具有不稳定 4f 壳的磁性有序 RE 化合物的“Kondo 项链”模型定性一致。

Their structures are related to those of a few binary AeTt3 (Ae = alkaline earth; Tt = Si, Ge; I4/mmm, tI32-YbSi3) compounds that are stable at high pressure, characterized by a more complex 3D covalently bonded Tt network.

  Phase equilibria in the Yb-Sn-Te ternary system were studied for the first time by physicochemical methods. Phase diagrams were constructed for the Yb-Sn binary subsystem and YbTe-SnTe, YbSn-SnTe, Yb(5)Sn(3)-YbTe, YbSn-YbSnTe(2), YbSnTe(2)-Te, Yb(5)Sn(3)-YbSnTe(2), Yb-SnTe, and YbSnTe(2)-Sn inner sections. A liquidus surface projection for the title system was constructed. The system was found to have the following features: one ternary compound of composition YbSnTe(2), which melts congruently at 1335 K, and extensive solid solutions based on SnTe and YbSnTe(2).

  Two new tertiary ytterbium transition metal stannides, namely, Yb3CoSn6 and Yb4Mn2Sn5, have been obtained by solid-state reactions of the corresponding pure elements in welded tantalum tubes at high temperature. Their crystal structures have been established by single-crystal X-ray diffraction studies. Yb3CoSn6 crystallizes in the orthorhombic space group Cmcm (no. 63) with cell parameters of a = 4.662(2), b = 15.964(6). c = 13.140(5) angstrom, V = 978.0(6) angstrom(3), and Z = 4. Its structure features a three-dimensional (3D) open-framework composed of unusual [CoSn3] layers interconnected by zigzag Sn chains, forming large tunnels along the c-axis which are Occupied by the ytterbium cations. Yb4Mn2Sn5 is monoclinic space group C2/m (no. 12) with cell parameters of a = 16 937(2). b = 4.5949(3), c = 7.6489(7) angstrom, 106.176(4), V = 571.70(8) angstrom(3), and Z = 2. It belongs to the Mg5Si6 structure type and its anionic Substructure is composed of parallel [Mn2Sn2] ladders interconnected by Unusual zigzag [Sn-3] chains, forming large tunnels along the c-axis. which are filled by the ytterbium cations. Band structure calculations based on density function theory methods were also made for both compounds. (C) 2008 Elsevier Inc. All rights reserved.
