摘要：
Giant magneto-impedance effect in multilayered film was investigated theoretically according to the classical electromagnetic theory. The theoretical results of multilayered film with transverse magnetic anisotropy show that, the maximum impedance occurs when magnetic field is close to the effective anisotropy field at high frequencies, smaller resistivity of the conducted layer would lead to a larger impedance change ratio in multilayered film. At 1 MHz the impedance change ratio in layered films is much larger than that in single film. The theoretical results agree qualitatively with experimental ones.
