Abstract

We investigate the impedance and direct-current (DC) electric response induced by ferromagnetic resonance (FMR) in a single layered ferromagnetic wire. The impedance difference in the FMR state rectifies part of the radio-frequency (RF) current and induces the DC voltage. The impedance measurement using a vector network analyzer reveals the characteristics of the rectifying effect. A phenomenological model interpreting the impedance changes derived from the magnetization precession is proposed. The rectifying effect lies in the ability to demodulate the RF signal for wireless mobile communications.
