Preparation, Phase Relation and Dielectric Properties of Y(1-x)LuxMnO3

采用固态化学反应方法制备了Y(1-x)LuxMnO3体系的系列样品. 利用粉末X射线衍射分析(XRD)和扫描电子显微镜(SEM), 研究了Y(1-x)LuxMnO3体系的样品形貌、相关系和固溶区范围. 采用Rietveld结构精修的方法研究了不同掺杂量对晶体结构的影响, 研究表明, 体系的固溶区范围大约为x=0.0～0.32. 介电性能表明: Lu3+离子的掺杂影响了样品的介电常数和介电损耗, 介电常数在固溶区范围达到最大值, 但掺杂量并未改变居里温度.
