Title: Structural, Magnetic, and Magentostrictive Properties of Dy{sub 1−x}(Tb{sub 0.2}Pr{sub 0.8}){sub x}Fe{sub 1.93} (0≤ x ≤ 0.5) Compounds

Abstract

The structural, magnetic, and magnetostrictive properties of light rare earth Pr-contained Dy{sub 1−x}(Tb{sub 0.2}Pr{sub 0.8}){sub x}Fe{sub 1.93} (0≤ x ≤ 0.5) compounds were investigated by means of X-ray diffraction, vibrating sample magnetometer and strain gauge technique. A single Laves phase with MgCu{sub 2}-type structure was obtained in the composition range of 0.0≤ x ≤ 0.25. The lattice parameter of the Lave phase increases with increasing x due to the large radius of Pr{sup 3+} and Tb{sup 3+}. The Curie temperature of the Laves phase decreases with increasing x, indicating weakening strength of 3d-4f coupling. The saturation magnetization decreases with increasing x, which could be ascribed to the opposite magnetic moment alignments of Pr and (Td,Dy) with Fe. The magnetostriction of Dy{sub 1−x}(Tb{sub 0.2}Pr{sub 0.8}){sub x}Fe{sub 1.93} increases with increasing x, peaks at x = 0.25 and then decreases with further increasing x.
