Abstract: Firstly, we reviewed the latest research and application progress of several main types of nano-ferrite based core-shell structured composite absorbing materials, introduced the corresponding preparation methods and their advantages and disadvantages. Secondly, we summarized the main problems in the research field of nano-ferrite based core-shell structured composite absorbing materials. Finally, we looked forward to the future research and development direction.

Key words: nano-ferrite, core-shell structure, composite absorbing material
