The magnetic hyperfine fields observed at the 57Fe nuclei (77 K) in the Dy(Mn1-xFex)2 and Dy(Fe1-xCox)2 intermetallics form a Slater-Pauling curve. In order to study the effect of cobalt atoms on crystal structure and hyperfine interactions, the new Co/Al substituted series Dy(Fe0.4Co0.6-xAlx)2 was prepared and data of X-ray powder analysis are presented (300 K). From the 57Fe Mössbauer measurements at 77 K the hyperfine parameters were obtained. The magnetic hyperfine fields form a branch of the Slater-Pauling curve.
