| Abstract | It was previously found, that the magnetic hyperfine fields observed at 57Fe nuclei (4.2 K) in the Dy(Mn 1−xFex)2 and Dy(Fe1−xCox)2 intermetallics form a Slater–Pauling curve. Both 3d sub-bands in the Dy(Mn 0.4Fe0.6)2 compound are filled up only partially with 3d electrons. The consequence of Fe/Al substitution, in the Dy(Mn 0.4Fe0.6)2 compound, was studied in the present paper. For this purpose the synthesis and X-ray analysis (300 K) of the series Dy(Mn 0.4Fe0.6−xAl x)2 were performed. The cubic, MgCu 2-type, Fd3m crystal structure was observed across the series. 57Fe Mössbauer effect measurements for the series were realized at 4.2 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. The data are qualitatively related to the Stoner model. © 2003 Elsevier B.V. All rights reserved. |
