Abstract: Status and progress on microwave ferrite materials by combining the developing trend of microwave ferrite devices at home and abroad were summarized.In terms of garnet-based materials,new formulas have been developed with low loss,high power,and low cost materials.For spinel-based materials,they were widely applied in millimeter wave devices and phase shift devices due to the broad magnetization and high remanence.Also,product performance and production capability were clarified.It was emphasized on the importance and necessarity for the development of new microstrip materials and low intermodulation materials as well as industrialization of ferrites.Meanwhile,research ideas and methods were indicated. 

Key words: microwave ferrite materials;garnets, spinel
