The ternary RE–Si–B systems (RE=Dy, Ho, Er and Y) at 1270K: Solid state phase equilibria and magnetic properties of the solid solution REB2−xSix (RE=Dy and Ho)
RE 5 Si 3 B x of Mn 5 Si 3 -type and the solidsolution REB 2− x Si x of AlB 2 -type. Prior to this work, the binary systems RE–Si and RE–B, which form the boundary of each diagram, were also re-investigated. In addition to the structures of RE 5 Si 3 (Mn 5 Si 3 -type, RE = Dy, Ho and Y) and Dy 3 Si 4 (Ho 3 Si 4 -type) which were previously reported or will be presented in a forthcoming paper, the
摘要 利用 X 射线衍射、扫描电子显微镜和电子探针微量分析等实验技术,在 1270 K 下测定了三元 RE-Si-B 图中的固态相平衡(RE = Dy、Ho、Er 和 Y)。通常,每个图都获得了三个三元相:具有四方对称性的线状化合物 RE 5 Si 2 B 8、Mn 5 Si 3 型的硼插入 Nowotny 相 RE 5 Si 3 B x 和固溶体 REB 2 - x Si x 的AlB 2 -型。在这项工作之前,还重新研究了构成每个图边界的二元系统 RE-Si 和 RE-B。除了先前报道或将在即将发表的报告中介绍的 RE 5 Si 3 (Mn 5 Si 3 型,RE = Dy、Ho 和 Y)和 Dy 3 Si 4(Ho 3 Si 4 型)的结构之外纸,RE 5 Si 4(Sm 5 Ge 4 型,RE = Dy 和 Ho)、DySi(CrB 型)和 HoSi 的 X 射线单晶结构在两种多晶型变体中,即

Details of the singlecrystalgrowth of incongruentlymeltingTbB6, DyB6, HoB6, and YB6using a crucible-free vertical floating zone method are reported. Magnetic susceptibility is reported and discussed. It is suggested that antiferro-quadrupolar ordering occurs in DyB6between 30 and 25.6 K.

was carried out of REB 50 ( RE = Tb , Dy ) compounds which have a new 9th type of structure of the B12icosahedralcompounds. Measurements of the static magnetic susceptibility of TbB50 at high fields confirmed the antiferromagnetic-like transition previously observed. A similar magnetic transition was also observed for DyB50 at 6.2 K. The REB50-type compounds are the first higher borides in which a magnetic
摘要 合成了新的第9类结构的B12二十面体化合物REB 50 ( RE = Tb , Dy ) 化合物。在高场下对 TbB50 的静磁化率的测量证实了先前观察到的类反铁磁转变。DyB50 在 6.2 K 时也观察到类似的磁跃迁。REB50 型化合物是第一个发生磁跃迁的高级硼化物。转变温度的差异表明 B12 二十面体轴的长度不能作为磁相互作用的唯一考虑因素。
