TL;DR: In this article, a small-signal approximation for a cylindrical magnetic conductor which is saturated along its axis by a static magnetic field is presented, and a comparison with high frequency impedance spectra of CoFeSiB wires measured with a network analyzer, including the observation of the ferromagnetic resonance peaks, confirms that the proposed model gives a satisfactory explanation for the linear GMI effect over a broad frequency range.

TL;DR: In this paper, it was shown that the giant magnetoimpedance (GMI) response of a plate or ribbon is rigorously equivalent to the response of the same sample in a FMR experiment.

TL;DR: Tunneling magnetoresistive (TMR) reading heads at an areal density of 80-100 Gbit/in/sup 2/ in a longitudinal magnetic recording mode have for the first time been commercialized for both laptop and desktop Seagate hard disk drive products as discussed by the authors.

TL;DR: An overview of ferromagnetic nanowire (FMNW) metamaterials is presented in this article, where the geometrical properties of the FMNW structure, such as the wire diameter and the wire nanodisk thicknesses, determine the dc and RF responses of the material.

TL;DR: In this paper, a theory of giant magnetoimpedance (GMI) in anisotropic magnetic wires is presented, which is valid over a broad field and frequency range.
