Abstract
The dipolar interactions were investigated through the giant magnetoimpedance effect in FINEMET/IGZO/CoFeSiB composite ribbons. The interface between the CoFeSiB film and FINEMET ribbon was separated by IGZO layer in FINEMET/IGZO/CoFeSiB composite ribbons, which effectively induced dipolar interactions. The dipolar interactions were analyzed by the peak position field (H p) of giant magnetoimpedance effect and magnetic properties. The results show that the H p decreased with the increase of the IGZO layer thickness. These results suggest that the GMI ratio (58%) and characteristic frequency (800 kHz) were optimized. The composite ribbons have high GMI ratio and low frequency, which can be applied in magnetic field sensors.
