A consequence of the Fe/Ni substitution in the Dy(Fe0.4Co0.6)2 compound was studied in the present paper. For this purpose the synthesis and X-ray analysis (295 K) of the Dy(Fe0.4 xNixCo0.6)2 series were performed. The cubic, MgCu2-type, Fd3m crystal structure was observed across the series. 57Fe Mössbauer effect spectra for the series were collected at 77 K. The obtained crystallographic data and the hyperfine interaction parameters are presented. The magnetic hyperfine fields form a separate branch of the Slater-Pauling curve known for the Dy(Mn1 xFex)2 and Dy(Fe1 xCox)2 series. The data are qualitatively related to the Stoner model.
