A simplified model is set up to study the high frequency response in a thin film head, where two pieces of Fe-Al-N films are placed parallel to each other with opposite alternating external magnetic field applied. In this model, the frequency response of magnetic clusters is calculated by a micromagnetic model based on the Landau-Lifshitz-Gilbert equations, and the initial permeability of mesoscopic Fe-Al-N thin films is analyzed in a wide frequency region from 10 to 5000 MHz. The model of a soft magnetic thin film is built up on the ripple structure of the anisotropy field of magnetic clusters. The magnetization interaction between the two Fe-Al-N films is carefully computed to find its effect on the frequency response. The frequency response in a single mesoscopic Fe-Al-N thin film is carefully studied in advance.
