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