单一掺杂对NiCuZn铁氧体的改性作用

Modification effects of single doping in NiCuZn ferrite

作为重要的软磁铁氧体材料,随着NiCuZn铁氧体应用的不断发展,对其性能也提出了更高的要求,掺杂是改良和提高软磁铁氧体性能的重要手段。本文归纳了单一掺杂在改良和提高NiCuZn铁氧体的主要性能方面的作用,如起始磁导率μi、品质因数Q、截止频率fr、居里温度TC以及密度ρ等,并简单介绍了穆斯堡尔谱在研究NiCuZn铁氧体的掺杂改性中的应用。

As an important kind of soft magnetic ferrite material,with the continuous development of NiCuZn ferrite applications,higher requirements for property is brought forwared,and doping is one of important means to improve and modify the performance of soft magnetic ferrite.This paper summarizes the modification and improvement effects of single-doping in the properties of NiCuZn ferrite,including initial permeability,quality factor,cut-off frequency,Curie temperature and density,etc.Also,the paper given a brief intruduction of application of Mossbauer spectra in the research of doping of NiCuZn ferrite.
