Abstract
This article reports on the relations between the high frequency characteristics and magnetic properties of multilayer CoFeN/native-oxide films prepared by radio frequency reactive magnetron sputtering in mixed argon and nitrogen gas atmosphere and exposure to oxygen in a sequence. The [CoFeN(20Ã
)/native-oxide]20 multilayers exhibit excellent soft magnetic properties in the as-deposited state, e.g. easy axis coercivity (Hc) below 1Â Oe and 4ÏMs of â¼22kG. The in-plane uniaxial anisotropy field (Hk) is as high as 67Â Oe. This large anisotropy field significantly enhances the ferromagnetic resonance frequency (fFMR) to â¼3GHz.
