The magnetoresistance contribution to the total magnetoimpedance of thin films: a simple model and experimental basis

Abstract The magnetoimpedance and magnetoresistance effects have been examined in a 1 μm Fe19Ni81 film. Noticeable longitudinal (∼1%) and transverse (∼2%) magnetoimpedance have been observed in the frequency range 20–25 MHz. A comparison between magnetoimpedance and magnetoresistance measurements leads us to conclude that magnetoresistance notably contributes to the magnetoimpedance and its hysteretic behaviour in a low-frequency limit.
