摘要(Abstract)：

以Fe_3O_4粉体,Y_2O_3∶3%(摩尔分数)Eu~(3+), 5%(摩尔分数)Tb~(3+)粉体和三聚氰胺为原料,采用微波烧结法制备FeYO_3/Y_2O_3∶3%Eu~(3+), 5%Tb~(3+)复合粉体,利用X射线衍射仪(XRD)对各种粉体的结构进行分析,利用扫描电镜(SEM)对复合粉体的形貌进行观察,并利用振动样品磁强计对复合粉体的磁学性能进行测试。结果表明:复合粉体均呈针状,长度和细度均为纳米级;当Fe_3O_4,Y_2O_3∶3%Eu~(3+), 5%Tb~(3+)和三聚氰胺摩尔比为1∶3∶4时,所制备的FeYO_3/Y_2O_3∶3%Eu~(3+), 5%Tb~(3+)粉体磁力最强,饱和磁化强度为3.852 emu·g~(-1),剩余磁化强度为0.6 emu/g,矫顽力为232 Oe。

关键词(KeyWords)： 微波烧结法;FeYO_3/Y_2O_3∶3%Eu~(3+),5%Tb~(3+);磁性
