“…The coercive force, H cm is varied in the range of (0.5-1.5) Oe at room temperature. In spite of a quite broad range of initial H cm -values, the correlation of H c /H cm remains unchanged within the error bars (-up to 20%) and fits within the dependence shown in Figure 5 [5][6][7][8].…”

“…Depending on the critical cooling rates, different metastable metal phases can be formed: the supersaturated solid solution, nanocrystalline, microcrystalline and crystalline phases. The values of the critical quenching (cooling) rates that gives rise to a metastable (or supersaturated) state of the microwire metallic core are 10 4 -10 7 K/s [2,6,7]. The main advantages of this method for the production of the cast glass-coated microwires are as follows [2,3,[5][6][7]]:…”

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.

Thin and flexible materials that can provide efficient electromagnetic interference (EMI) shielding are urgently needed, particularly those that can be rapidly processed and withstand harsh environments. Cobalt‐based metallic glasses stand out as prime candidates due to their excellent soft magnetic properties, satisfactory shielding features, and mechanical properties. Herein, a recently developed technique is used to fabricate metallic glass microfibers from Co66Fe4Mo2Si16B12 alloy. The produced microfibers are characterized for their size and uniformity by scanning electron microscopy and their amorphous structure is confirmed by X‐ray diffraction (XRD) and differential scanning calorimetry (DSC). The cobalt‐based metallic glass microfibers show an EMI shielding factor that reaches five in the static regime and obtains an up to 25‐fold increase of the attenuation constant in the Ku frequency band. This performance originates from the combination of soft magnetic properties and excellent electrical conductivity. In addition, the flexible microfibers exhibit excellent hardness and elasticity making them suitable for EMI shielding of complex geometries. Their hardness and elastic modulus are measured by nanoindentation to be 11.31 ± 0.60 GPa, and 110.54 ± 11.24 GPa, respectively.
