| Abstract: | In this paper,the recent development of ferrite thin film with high permeability at microwave frequency is mainly introduced.For spinel ferrite film,focuses are concentrated on Ni-Zn and Li ferrite film,the effect of spray technics and Co2 adulteration on the microwave magnetic properties are introduced,and the mechanism of high permeability at microwave frequency is analyzed.For hexagonal barium ferrites,resonance characteristic of BaCoxTixFe12-2xO19 ferrite film and the effect of underlayer on forming BaM hexangular structure was mostly described,in addition,(Zn1-xCox)2-W ferrite film is introduced.Finally,the problems and applications prosrect of ferrite films at microwave frequency were presented. |
