“…Currently, there are basically two methods of wire fabrication techniques. The first one utilises in-water-spinning method for which as-cast wires have a diameter of 125 microns (Ogasawara & Ueno, 1995). The wires then cold drawn down to 20 -30 m, and finally annealed under stress to established a needed anisotropy.…”

“…Moreover the technology of melt quenching (also known as rapid quenching) is not expensive and rather fast [1,2,[5][6][7]. Cylindrical symmetry of melt quenched magnetic wires allows considerable enhancement of GMI effect and single DW velocity as compared to other families of soft magnetic materials [8].…”

We present an overview of the factors affecting soft magnetic properties, fast domain wall propagation and giant magnetoimpedance (GMI) effect in thin amorphous wires. The magnetoelastic anisotropy is one of the most important parameters that determine the magnetic properties of glass-coated microwires and therefore annealing can be very effective for manipulation the magnetic properties of amorphous ferromagnetic glass-coated microwires. Increasing of DW velocity in Fe-rich and Fe-Ni based (low Ni content) microwires is achieved after annealing. After heat treatment of Co-rich microwires we can observe transformation of inclined hysteresis loops to rectangular and coexistence of fast magnetization switching and GMI effect in the same sample. On the other hand stress annealing of Fe-and Co-rich microwires allows achievement of considerable magnetic softening and GMI effect enhancement.

The most relevant aspects of magnetic amorphous microwires are collected in this chapter from production and processing methods to micromagnetic magnetization reversal processes, including selected technological applications finally paying particular attention to the actual search for novel microwire materials. After a first general review of the present state of the art in Section 1, the fabrication of amorphous and nanocrystalline microwires by rapid solidification techniques and subsequent processing is described in Section 2, including important characteristics such as mechanical stress distribution. Section 3 reviews the most interesting magnetic features of positive magnetostriction, Fe‐based microwires with bistable magnetic behavior such as: domain structure, magnetization reversal mechanism and its dynamics, magnetoelastic behavior, magnetostatic interactions in arrays of bistable microwires, and applications. Section 4 is devoted to the circular magnetization process and magnetoimpedance effect of nonmagnetostrictive microwires, the microwave properties, and their applications. Finally, Section 5 summarizes the latest results obtained in the search for novel microwires with new and/or optimized properties: nanocomposite and multilayer microwires.
