Magnetic properties of amorphous wires with different diameters

Influence of microstructure evolution on GMI properties and magnetic domains of melt-extracted Zr-doped amorphous wires with accumulated DC annealing

“…Co-based amorphous wires with excellent giant magneto-impedance (GMI) properties have recently attracted much attention due to their potential applications, especially as GMI sensor elements for detecting very slight magnetic fields [1][2][3][4][5]. The principal source of GMI effect is accordingly ascribed to the typical skin effect, which means AC current flows only in the outer region of the magnetic materials at relatively higher frequency.…”

Biased magnetization reversal in bi-phase multilayer microwires

“…Contrary to the academic trend, the attention for these materials shown by the industrial world is steadily increasing as their technological potential is realized. Their main employment can be found in sensing application, particularly in the fields of automotive, mobile communication, medical and home appliance industries [1][2][3][4]. Moreover, this family of materials is very promising for spintronic devices in magnetic recording media [5].…”

Liquid pressure wireless sensor based on magnetostrictive microwires for applications in cardiovascular localized diagnostic

“…[8][9][10] While the metallic core provides the magnetic behavior, the cover has a protective and stress-inducting function. Due to its tiny dimensions and its particular effects like Giant Magnetoimpedance (GMI), [11][12][13][14][15][16][17] bistability, 18 ferromagnetic resonance 19 and magnetoelasticity, 20 these materials have been considered as promising sensor elements. Furthermore, since the metallic core is covered by a biocompatible pyrex shell, they are suitable for biological and medical applications.…”
