THE SYSTEM NEODYMIUM - MANGANESE (STRUCTURES, MAGNETIC PROPERTIES, PHASE DIAGRAM), THE PHASE DIAGRAMS YB-HG AND TB-HG,

Abstract

The system Nd-Mn was investigated by X-ray diffraction, X-ray fluorescence analysis, differential thermal analysis and magnetic analysis. The phases present were determined and their structures established: Nd6Mn23 possesses the Th6Mn23, NdMn12 the ThMn12 structure. The magnetic properties of NdMn2, Nd6Mn23 and NdMn12 could be evaluated. Nd6Mn23 is ferromagnetic, NdMn12 is antiferromagnetic. By measurements of the magnetization and of the susceptibility the mu- and mu(eff)-values could be determined. By differential thermal analysis and by the amalgam process the systems Tb-Hg and Yb-Hg could be evaluated. The phases TbHg, TbHg2, TbHg3, YbHg, YbHg2 and YbHg3 could be prepared mostly for the first time and their structures have been determined. Both binary Hg-systems of Tb and Yb are similar, although the Tb-Mn and Yb-Mn systems differ considerably. (Author)
