Abstract

A series of hexagonal perovskite-type compounds Yb_1−xDy_xMnO₃ (0.1 ≤ x ≤ 0.5) have been prepared by the traditional solid-state reaction method at 1573 K, and a single crystal orthorhombic perovskite-type compound Yb_0.5Dy_0.5MnO₃ has also been obtained by a high-pressure flux method at 1273 K under 5 GPa high pressure. Final products are fully characterized by XRD and XPS analyses, and then subject to magnetic measurements. It appears that the hexagonal Yb_1−xDy_xMnO₃ (0.1 ≤ x ≤ 0.5) compounds have shown antiferromagnetic properties with a Néel temperature of 10 K, and canted antiferromagnetic behaviour is clearly evident at a lower temperature. Also, it is found that the magnetization of Yb_1−xDy_xMnO₃ increases with the increase of Dy content. The orthorhombic Yb_0.5Dy_0.5MnO₃ single crystal has been found to be paramagnetic, differing from RMnO₃ reported in the literature, which is antiferromagnetic due to subtle structural difference.
