Development of ferromagnetic thin films with high permeability at GHz frequency

LU Hai-peng,DENG Long-jiang,CHEN Liang (School of Microelectronics and Soli-state Electronics,UESTC,Chengdu 610054,China)  
Recent research progress in ferromagnetic films with high permeability at microwave frequency was summarized in this paper.The research of ferromagnetic films deposited on thin flexible substrates was mainly focused on Fe-based and Co-based alloys,and the influence of components on these films was discussed.As far as nanocrystalline Fe-N and FeXN films were concerned,the role of different FeN phases was described.For T-M-O magnetic nano-granular films,the mechanism of high permeability at GHz frequency was analysed.The promoting applications of ferromagnetic films at GHz frequency were presented,as well as the challenges in future development.
