| 摘 要： | 采用传统固相法,制备了Sm3+掺杂的MnZn铁氧体。借助XRD、SEM和Agilent 8722 ET网络分析仪等表征手段,研究了微量Sm3+掺杂对其显微结构及电磁性能的影响。结果表明,当n(Sm3+)为0.03mol,其晶格常数a增加到0.84491nm。当n(Sm3+)为0.03mol,MnZn铁氧体的复介电常数和复磁导率显著提高,ε″和μ″损耗峰值分别提高到2.15和5.52。

| Abstract: | MnZn ferrites doped with Sm3+ were prepared by the conventional solid phase method.Its microstructure and electromagnetic properties were investigated using XRD,SEM and network analyzer(Agilent 8722 ET) etc.Obtained results show that the lattice parameter a of the ferrites increases to 0.844 91 nm when doped amounts of Sm3+ is 0.03 mol.Complex permittivity and complex permeability increase significantly after doping n(Sm3+) = 0.03 mol,and the maxima of ε' and μ' are enhanced to 2.15 and 5.52,respectively. |
