Abstract

The planar structure with a radial current distribution is suggested for sensor applications and is investigated both theoretically and experimentally. The studied structure consists of two identical ferromagnetic disks separated by a dielectric layer. The modified construction of the magnetoimpedance sensor may help to avoid the appearance of parasitic effects caused by the intrinsic magnetic field of the sensitive element. The strong changes in the impedance of the structure on frequency and permeability value were predicted. The theoretical estimation was qualitatively confirmed by experimental results for the model samples.
