摘　　要：NiZn尖晶石铁氧体具有优良的高频特性,应用频带宽,高电阻率,制备工艺简单等特性,NiZn铁氧体适用于各种电感器,通信、广播、磁记录、医学生物等领域得到广泛应用。国内外对NiZn铁氧体的磁学方面,应用及制备工艺有大量的研究,但是借助穆斯堡尔谱分析内部结构,离子是怎样占位的,及离子的占位是怎样影响宏观磁性的研究并不多。本论文用传统的机械氧化法制备NiZn,及掺杂0.15 mol/L Mn的尖晶石铁氧体,使用高分辨率的穆斯堡尔谱测试仪器,研究铁氧体离子分布及与内部原子相互作用的变化,从微观结构上分析宏观磁性能变化的原因。NiZn spinel ferrite has excellent high frequency characteristics,application frequency bandwidth,high resistivity,simple preparation process,etc.It is widely used various inductors,communication,broadcasting,magnetic recording,medical biology,etc.There has been a great deal of researchs on the magnetic aspects,applications and preparation processes of NiZn ferrite.But how the ions occupy the position and how the occupation of ions affect the macroscopic magnetism by Mossbauer spectroscopy.Not much research.In this paper,NiZn and Mn-doped spinel ferrite were prepared by conventional mechanical oxidation method.The high-resolution Mossbauer spectrometer was used to study the distribution of ferrite ions and the interaction with internal atoms.And we explain the change of macroscopic magnetic property.
