 note = {A relation between high-frequency properties, and angle theta of the easy axis in soft magnetic film and ac applied field was investigated in order to fabricate the film for RF spiral inductor without a localized EMI (Electro-Magnetic Interference). This relationship was measured using a soft CoFeSiO/SiO2 granular multilayer magnetic thin film and simulated by using LLG (Landau-Lifshitz-Gilbert) micromagnetic simulator. The measured and calculated frequency dependence of the film's complex relative permeability, mu(r)' and mu(r)'' compared well with 10% mean error. The real part of complex relative permeability mu(r)' was dependent on approximately sin(2) theta. The ferromagnetic resonance (FMR) frequency, f(r), and the FMR half-width, Delta f(r) were not dependent on the angle theta. They were estimated to be 2.54 GHz and 0.3 GHz, respectively. These results are significant for the design of various magnetic thin film spiral inductors in RF integrated circuits without localized EMI., Article, IEEE TRANSACTIONS ON MAGNETICS. 48(11):4515-4517 (2012)},
