Abstract:

为了探究碱土金属离子掺杂对BiFeO_3陶瓷多铁性的影响,采用固相法成功制备了BiFeO_3以及Bi_(0.9)A_(0.1)FeO_3(A=Ca、Sr、Ba)陶瓷,并对其铁电、铁磁等性能进行了研究.X射线衍射结果表明:晶体均为六方钙钛矿结构,空间群为R3c,晶胞参数随掺杂离子半径的增大呈现先增大后减小的现象.电学性能测试发现:Bi_(0.9)A_(0.1)FeO_3陶瓷的铁电极化值和漏电流密度均随着掺杂离子半径的增大而增大.结合X射线光电子谱(X-ray photoelectron spectroscopy,XPS)铁离子价态分析表明:Bi_(0.9)A_(0.1)FeO_3陶瓷铁电性会受掺...
