Abstract

A high sensitive detection of reversible susceptibility in magnetic thin films was performed with an electric circuit resonant technique. A multilayer sample of [NiFe(100 nm)/Cu(10 nm)]5 exihibits the most sensitive modulation effect among the fabricated samples. That is, the resonance frequency fr, was decreased with the bias field Hb from 9.3 (Hb=0 Oe) to 8.6 MHz (Hb=6.0 Oe) at an exciting field Hex=70 mOe. The marked fr change can be associated with the field-induced susceptibility modulation in the soft magnetic thin film.
