| Abstract: | In this study, the sample of equivalent LC parallel circuit was composed of Fe-based multilayered films, the field dependence of resonance frequency and impedance were measured in the sample, respectively, the reason of magnetic frequency shift was analyzed, the giant magneto-impedance in the resonant state of sample was investigated, and the maximum impedance ratio in the inherent resonant state of sample was obtained from experimental data, indicating a distinctive frequency selectivity of the sample＇s giant magneto-impedance effect. |
