Glass-coated microwires obtained by a quenching-and-drawing
technique (also labelled Taylor-Ulitovsky method) have attracted the
attention in the last recent tears regarding their magnetic, magnetoelastic
and magnetotransport properties as well as their promising technological
applications. These microwires consist of a metallic nucleus covered by a
Pyrex-like these new magnetic microwire-shaped materials result to be very
adequate materials to investigate fundamental aspects concerning the
mechanisms governing their macroscopic magnetic properties. In this talk I
will present the most relevant features on the research of magnetic,
magnetoelastic and magnetotransport properties of amorphous ferromagnetic
glass-coated microwires exhibiting giant magnetoimpedance effect (GMI).
GMI application to the sensor industry will be presented together with
advantages and disadvantages of their use. In addition, new applications of
exchange bias effect in thin films technology will be proposed for GMI
sensors applications as a way to reduce energy and simplify the electronic
circuit.
