Magnetoinductance and magnetoimpedance response of Co-based multi-wire arrays

请选择邀稿期刊:
摘要: The magnetic circular permeability extracted from impedance measurements of arrays composed of Co- based amorphous wires was studied as a function of the number and distance between the wires. The results showed that a linear array with higher number of wires increased the permeability and thereby magnetoimpedance (MI) response up to 10 MHz. It was also proposed that such variation in circular permeability originated from the magnetostatic interaction among the wires gave rise to a change in the skin depth and finally in impedance. Increasing the distance between the wires had a detrimental effect on permeability and MI ratio due to a weaker mutual interaction. These observations provide support to the complex inductance formalism as an alternative approach to explain MI change in wire arrays.
