中文摘要	Rare-earth ion Dy was substituted at the bismuth site in BiFeO3 to produce Bi1-xDyxFeO3 (x = 0, 0.1. 0.2 and 0.3) polycrystalline ceramics. A two-stage solid-state reaction method was adopted in synthesizing the materials. The effects of varying the Dy doping concentration on the crystalline structures, morphologies and magnetic properties of the final products have been investigated. It is found that Dy doping resulted in a sequence of structural phase transitions and led to small grain sizes in the materials. As a result, the magnetic property of the doped samples was much enhanced. Therefore, it seems a promising way to improve the weak ferromagnetic property of BiFeO3 based materials by Dy doping.
