We have investigated the effect of Co(Cr) substitution on magnetic properties of as-deposited Fe–Hf–N films. 4πMs increases with increasing Co content (3–16 at. %) and decreases with increasing Cr content. The film Fe56Co16Hf10N18(at. %) shows excellent soft magnetic properties, with 4πMs∼16.8 kG, Hc∼0.25 Oe, and effective permeability ∼4200 at 100 MHz. In Fe71Cr3Hf9N17, the permeability is about 5200 at 100 MHz, while the values of 4πMs and Hc are ∼14.6 kG and 0.5 Oe, respectively. In order to estimate the magnetic anisotropy, the angular dependency of the resonance magnetic field and linewidth were observed by ferromagnetic resonance (FMR) at 9.84 GHz. The Fe56Co16Hf10N18 film shows a single resonance peak, whereas the as-deposited Fe–Hf–N films shows weak secondary peaks. © 2000 American Institute of Physics.
