“…[20][21][22] Recently, it has been found that inserting an insulating layer between magnetic layers can further increase the GMI. [23][24][25] This study did not clarify the further increase of the GMI from the perspective of magnetic interactions. However, that study gave ideas for using composite materials in structural designs.…”

The dipolar interactions were investigated through the asymmetric magnetoimpedance in FINEMET/SiO2/FePd composite ribbons. The interface between the hard (FePd layer) and soft (FINEMET ribbon) phases was coherent by SiO2 layer in FINEMET/SiO2/FePd composite ribbons, which effectively induced dipolar interactions. The contribution of dipolar interactions to the bias field (H b ) by asymmetrical giant magnetoimpedance and magnetic properties was analyzed. The results show that H b response decreases with the increase of the SiO2 layer thickness. It indicated that the linear region near-zero field can be tuned by the thickness of SiO2 layer. These results allowed the GMI ratio (58 %) and characteristic frequency (500 kHz) were optimized. The transverse and longitudinal magnetic domain structure of FINEMET ribbon and FePd film were confirmed, respectively. The composite ribbons with high GMI ratio and low frequency can apply in linear magnetic sensors.

“…In recent research, more attention has been paid to the GMI effect in composite wires with insulator layers. Wang et al [8,9] studied the GMI effect in CuBe/ Insulator/NiFeB composite wires prepared by electroless deposition. Buznikov et al [10] developed a theoretical analysis on the effect of insulator layers on GMI in composite wires.…”
