“…It can be seen that in a wide x range, good high-frequency properties are obtained for (Ni 75 Fe 25 ) x (ZnO) 1−x films, suggesting that excellent high-frequency properties may be realized in other MSCGF systems, such as FeCo-SnO 2 , etc. For the typical sample with x = 0.74, it is seen that the μ is more than 200 below 1.0 GHz, while the imaginary part μ is much smaller than μ when f < 1.0 GHz and gradually increases to a maximum at f = 1.32 GHz which can be ascribed to the ferromagnetic resonance FMR [15] The experimental curves were fitted with formulas (2)-(4) quite well as shown by the solid lines. For the sample with x = 0.74, 4πM s = 7900 Gs and H k = 26 Oe, according to formula (4), the FMR frequency f r is approximately 1.30 GHz, consistent with the experiment result.…”
