The films, prepared by rf magnetron sputtering, consisted of nanosized grains of FeCo as well as a Si and N rich intergranular amorphous phase. The Si concentration had a significant effect on the crystal structure of the FeCo phase. The resistivities of the Fe-Co-Si-N films were significantly enhanced by an increase in Si concentration. The resonant frequency of the Fe-Co-Si-N films could be tuned from 0.45 GHz to 2.1 GHz by controlling Si concentration. The N concentration greatly influenced magnetic properties and the variation in resonant frequency is in agreement with Kittel's equation. © 2010 Springer-Verlag. | Source Title: | Applied Physics A: Materials Science and Processing | URI: | http://scholarbank.nus.edu.sg/handle/10635/27423 | ISSN: | 09478396 14320630 |
