英文摘要: Abstract(#br)A Series of LuMn 1−x Ru x O 3 (0 ≤ x ≤ 0.3) samples were prepared by traditional solid-state reaction method. The interactions between Ru 3+ (with 4d electrons) and Mn 3+ (with 3d electrons) on the structure and magnetic properties of LuMn 1−x Ru x O 3 were investigated. The results of structural investigation reveal that samples crystallize in a single hexagonal structure with P6 3 cm group for LuMn 1−x Ru x O 3 samples with x ≤ 0.1. The change of Mn–O bond lengths and Mn–O–Mn bond angles indicates the trimerization of Mn 3+ ions is weakened and the tilting angle of MnO 5 bipyramids is decreased. The temperature dependence on magnetization M(T) curves prove that weak ferromagnetism (FM) exists in the samples. Meanwhile, the antiferromagnetic (AFM) transition temperature T N...
