Mn-Zn ferrite material is a kind of soft magnetic material with many categories,wide applications and large amounts.The temperature characteristics of the material determine its working temperature range,so it must be strictly controlled.The temperature characteristics of Mn-Zn ferrite materials mainly depend on the position of the Curie temperature and the second peak temperature,that is,the strength of the super-exchange between magnetic ions at the A and B sites in the crystal structure,and the compensation of the magneto crystalline anisotropy constant K1.This review mainly introduces the influence of main formula,preparation process and doping on Curie temperature and the second peak temperature,puts forward a method to quickly determine the main formula according to empirical calculation formula of Curie temperature and second peak temperature,and points out the correlation between Co2+overcompensation and Fe2+content.
