Magnetic Properties of $Tb_{1 - x}Y_{x}$ NiIn System

Polycrystalline samples of $Tb_{1 - x}Y_{x}NiIn$ (x = 0.2 and 0.4) were prepared and studied by powder X-ray diffraction and AC and DC magnetic measurements. The compounds crystallize in the hexagonal ZrNiAl-type structure. At low temperatures the ferromagnetic properties are detected. With increasing Y content a change in the magnetic properties, decrease of the Curie temperatures and magnetic moment in the ordered state are observed.
