Abstract
It was previously found that the magnetic hyperfine fields observed at Fe-57 nuclei (4.2 K) in the Dy(Mn1-xFex)(2) and Dy(Fe1-xCox)(2) intermetallics form a Slater-Pauling curve. Both 3d subbands in the Dy(Mn0.4Fe0.6)(2) compound are filled up only partially with 3d electrons. The consequence of Mn/Al substitution, in the Dy(Mn0.4Fe0.6)(2) compound was studied in the present paper. For this purpose the synthesis and X-ray analysis (300 K) of the series Dy(Mn0.4-xAlxFe0.6)(2) were performed. The cubic, MgCu2-type Fd3m crystal structure was observed across the series. Nevertheless for x = 0.35 and 0.40 a stoichiometric admixture of the hexagonal, MgZn2-type, P6(3)/mmc was evidenced. Fe-57 Mossbauer effect measurements for the series were performed at 4.2 K. The magnetic hyperfine fields form a separate branch of the Slater-Pauling curve. This branch is compared to the magnetic hyperfine field previously obtained for the Dy(Mn0.4Fe0.6-xAlx)(2) series (the Fe/Al substitution). The possible 3d electron band structure is discussed qualitatively within the Stoner model. (C) 2004 Elsevier B.V. All rights reserved.
