Isothermal section of the Dy-Ni-In system at T = 870 K has been constructed. Twelve compounds exist in the system, namely: DyNi9In2, Dy4Ni10.80In20.20, DyNi4In, DyNiIn2, DyNi1−xIn1+x (x = 0÷0.4), Dy2Ni2In, Dy2Ni2−xIn (x = 0.22), Dy5Ni2In4, Dy11Ni4In9, Dy6Ni2.34In0.66, ∼Dy67Ni22In11 and Dy13.60Ni3.34In3.06. Previously reported Dy10Ni9In20 and Dy3Ni2In4 compounds exist at higher temperature. The Ni/In substitution was observed for DyNi1−xIn1+x (x = 0÷0.4) and the Dy/In for Dy1−xNi2Inx (x = 0÷0.5) solutions. Solid solution DyxNiIn1−y, based on binary NiIn, extends up to 8 at.% Dy. Crystal structure of this solution at the composition Dy0.13NiIn0.93 was studied by single crystal and powder X-ray diffraction. Magnetic properties of numerous Dy-Ni-In compounds have been reviewed as well.
