摘要
Numerical computations have been used to study the magnetoimpedance (MI) effect in magnetic wires and microtubes. Two kinds of wires have been investigated. In the first case, a typical amorphous wire with a core-shell structure is simulated, considering the different magnetization curve of each layer, and in the second case, a nonmagnetic wire with a thin deposited layer of magnetic material is studied. The results of the simulations agree in both cases with the experimental behavior usually found for these samples. They also allow us to explain such features as MI saturation and the influence of the resistivities of the conductive and magnetic layers in microtubes, that can improve MI-based devices.
