Abstract
Magnetic properties of cast amorphous and nanocrystalline microwires have been reviewed considering their potential application. Microwires were produced from Co Fe Mn Cr Cu B and Si using the Taylor–Ulitovsky method. Technological aspects of the Taylor–Ulitovsky method for fabrication of glass-coated microwire with different structure are analyzed. Magnetic microwires demonstrate a large variety of magnetic behaviors, which is important for sensing applications. Depending on the chemical composition of the metallic core, for Co-, Fe- and Ni-based composition, the microwires’ properties are very different. The geometrical characteristics (diameter of metallic core and thickness of the glass) of the microwire depend on the physical properties of a metallic composition and of glass and the parameters of the heating inductor and the speed of obtaining a microwire. The diameter of metallic core in these microwires can range from 0.5 to 70 μm, and their thickness of the glass can vary from 1 to 50 μm.

Summary
Cast glass-coated amorphous micro- and nanowires (CGCAMNW) are very interesting materials from a theoretical standpoint as well as for the practical applications. If a continuous production process of casting glass-coated amorphous magnetic microwires is carried out, a metal alloy rod (named LM) is inserted into the glass tube 1. This machine can produce cast glass-coated microwires of different types with a broad range of the core diameters, as was indicated above. 3 shows the machine for the preparation of CGCFMWs by the Taylor–Ulitovsky method, which were manufactured in This machine can produce cast glass-coated microwires of different types with a broad range of the core diameters, as was indicated above. of 12 method, Crystals.
