  Structure and magnetism of R5Bi3 (R=Tb, Dy, Ho, Er) and Tb4Bi3

  摘要：

  The physical properties of the rare earth bismuthides R5Bi3 (R=Tb, Dy, Ho, Er) and Tb,Bi, were investigated for the first time. The R5Bi3 compounds have been found to crystallise in the orthorhombic structure of the Y5Bi3-type whereas Tb4Bi3 forms the cubic anti-P4Th3 structure. The temperature dependence of the DC and AC magnetic susceptibility and the electrical resistivity have been measured. Tb4Bi3 orders ferromagnetically at 190 K whereas R5Bi3 show a complex form of magnetic ordering at lower temperatures. (C) 2001 Elsevier Science B.V. All rights reserved.

  A powder X-ray diffraction investigation of new Yb5Sb3-type R5TBi3-x and R5TxSb3-x solid solutions is reported. Substitution of Sb or Bi for transition metals leads to the distortion of the initial unit cell. The distortion of the initial unit cell is anisotropic: the cell parameter a increases while the cell parameters b and c decrease with decreasing unit cell volume.The Dy5CoBi2, Ho5CoBi2 and Er5CoBi2 compounds demonstrate a magnetic transition at 34(4), 25(4) and 20(2) K, respectively. The temperature of the magnetic transition of these solid solutions are close to the Dy5Bi3, Ho5Bi3 and Er5Bi3 compounds, respectively. (c) 2004 Elsevier B.V. All rights reserved.

  The syntheses and distributions of binary R(5)Pn(3) phases among the hexagonal Mn5Si3 (M), and the very similar orthorhombic beta-Yb5Sb3 (Y) and Y5Bi3 (YB) structure types have been studied for R = Y, Gd-Lu and Pn = Sb, Bi. Literature reports of M and YB-type structure distributions among R5Pn3 phases, R = Y, Gd-Ho, are generally confirmed. The reported M-type Er5Sb3 could not be reproduced. Alternate stabilization of Y-type structures by interstitials H or F has been disproved for these nominally trivalent metal pnictides. Single crystal structures are reported for (a) the low temperature YB form of Er5Sb3 (Pnma, a = 7.9646(9) angstrom, b = 9.176(1) angstrom, c = 11.662(1) angstrom), (b) the YB- and high temperature Y-types of Tm5Sb3 (both Pnma, a = 7.9262(5), 11.6034(5) angstrom, b = 9.1375(6), 9.1077(4) angstrom, c = 11.6013(7), 7.9841(4) angstrom, respectively), and (c) the YB structure of Lu5Sb3, a = 7.8847(4) angstrom, b = 9.0770(5) angstrom, c = 11.5055(6) angstrom. Reversible, temperature-driven phase transitions (beta-Yb5Sb3 reversible arrow Y5Bi3 types) for the former Er5Sb3 and Tm5Sb3 around 1100 degrees C and the means of quenching the high temperature Y form, have been esstablished. According to their magnetic susceptibilities, YB-types of Er5Sb3 and Tm5Sb3 contain trivalent cations. Tight-binding linear muff in-tin-orbital method within the atomic sphere approximation (TB-LMTO-ASA) calculations for the two structures of Tm5Sb3 reveal generally similar electronic structures but with subtle Tm-Tm differences supporting their relative stabilities. The ambient temperature YB-Tm5Sb3 shows a deep pseudogap at E-F, approaching that of a closed shell electronic state. Short R-R bonds (3.25-3.29 angstrom) contribute markedly to the structural stabilities of both types. The Y-type structure of Tm5Sb3 shows both close structural parallels to, and bonding contrasts with, the nominally isotypic, stuffed Ca5Bi3D and its analogues. Some contradictions in the literature are discussed.
