Magnetic properties and giant magnetoimpedance effect for CoFeMoSiB surface modified amorphous ribbons covered by water based ferrofluid

open access: yesEPJ Web of Conferences, 2018
Giant magnetoimpedance (GMI) effect is a powerful technique for magnetic label detection. Co-based amorphous ribbons are cheap materials showing high GMI effect at low operation frequencies for close to zero magnitostriction compositions.

Giant Magnetoimpedance Receiver With a Double-Superheterodyne Topology for Magnetic Communication

open access: yesIEEE Access, 2021
Radio reception relies on the medium which determines the propagation characteristics of the electromagnetic fields carrying the information. The permittivity varies greatly depending on the medium, but it remains nearly constant, except when magnetic ...

GMI Effect of Ultra-Soft Magnetic Soft Amorphous Microwires [PDF]

open access: yesThe Open Materials Science Journal, 2012
In this paper we experimentally studied GMI effect and soft magnetic behavior of Co-rich microwires. Correlation between magnetoelastic anisotropy and magnetic field dependences of diagonal and off-diagonal impedance components are observed. Low field GMI hysteresis, explained in terms of magnetoelastic anisotropy of microwires, has been suppressed by ...
