The series of amorphous ferromagnetic glass-coated microwires of composition Co69Fe4Cr4Si12B11, manufactured by Taylor-Ulitovsky technique, was investigated. The series consisted of six types microwires fabricated under different technological conditions. The metallic nucleus and glass coating diameters of microwires ranged within 11-20 μm and 26-35 μm, respectively. Investigation of the magnetic properties
of microwires was carried out using induction and the small-angle magnetization rotation techniques. The anisotropy field, the magnetostriction constant and the average value of the quenching stresses are estimated for all types of microwires. Based on the experimental data obtained, influence of technological parameters on
the microwire’s magnetic properties was investigated.
