摘要
采用溶胶凝胶法制备了La2/3Sr1/3Mn1-xCuxO3(x=0,0.05,0.10,0.20)的多晶样品.利用振动样品磁强计测量了样品在室温下的磁性能;利用X射线衍射确定了粉体的组成;利用扫描电子显微镜观察了颗粒的形貌.
La_(2/3)Sr_(1/3)MnO_3 polycrystalline powers were prepared by sol-gel method.The magnetic property of powders was characterized using vibrating sample magnetometer.The phase structure was presented by X-ray diffractometer.In addition,the morphology of the powders grain was observed by scan electron microscope.
