The Dy-Ni-Si system has been investigated at 1070 K by X-ray and microprobe analysis. The system contains the 12 known compounds DyNi10Si2, DyNi5Si3, DyNi6Si6, DyNi4Si, DyNi2Si2, Dy2Ni3Si5, DyNiSi3, Dy3Ni6Si2, DyNiSi2, DyNiSi, Dy3NiSi3, Dy3NiSi2, and the new compounds Dy34Ni16-27Si50-39, Dy2Ni15.2-14.1Si1.8-2.9, ~Dy11Ni65Si24, ~Dy16Ni62Si22, DyNi7Si6, Dy3Ni8Si, DyNi2Si, ~Dy40Ni47Si13 and ~Dy5Ni2Si3. Quasi-binary solid solutions were detected for Dy2Ni17, DyNi5, DyNi7, DyNi3, DyNi2, DyNi, DySi2 and DySi1.67.

Abstract
The Dy-Ni-Si system has been investigated at 1070 K by X-ray and microprobe analysis. The system contains the 12 known compounds DyNi10Si2, DyNi5Si3, DyNi6Si6, DyNi4Si, DyNi2Si2, Dy2Ni3Si5, DyNiSi3, Dy3Ni6Si2, DyNiSi2, DyNiSi, Dy3NiSi3, Dy3NiSi2, and the new compounds Dy34Ni16-27Si50-39, Dy2Ni15.2-14.1Si1.8-2.9, ~Dy11Ni65Si24, ~Dy16Ni62Si22, DyNi7Si6, Dy3Ni8Si, DyNi2Si, ~Dy40Ni47Si13 and ~Dy5Ni2Si3. Quasi-binary solid solutions were detected for Dy2Ni17, DyNi5, DyNi7, DyNi3, DyNi2, DyNi, DySi2 and DySi1.67. The crystal structures and magnetic properties of new phases RNi7Si6 (GdNi7Si6-type), R3Ni8Si (Ce3Co8Si-type), RNi2Si (YPd2Si-type) and R3Ni12Si4 (Gd3Ru4Al12-type), with R=Y, Gd-Tm, are also reported.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
