Features of the Structural and Magnetic Characteristics of Cobalt-Rich Amorphous Thick Microwires

Results are presented from investigating the structural and magnetic characteristics of Co69Fe4Cr4Si12B11 amorphous microwires with magnetic core diameters of 35–360 µm, obtained using an updated Ulitovskii–Taylor approach. It is found that the microwires have stable geometric dimensions along their lengths and almost defect-free surfaces. They are characterized by high plasticity and strength, and their magnetic characteristics depend on their diameter. The possibility of the microwires’ practical application is shown.
