Abstract
In this article the results on the detailed investigation of the structural, elastic and magnetic properties of the “thick” Fe73,5Si13,5B9Nb3Cu1 and Fe31Co34Ni10(SiB)25 amorphous microwires with the glass shell, produced by the modernized Ulitovsky–Tailor method, are presented. The diameter of the metallic core of microwires was varied from 50 to 200µm. It was found that the core has the stable geometric parameters along the microwire length and the smooth (almost without defects) surface. The studied samples are characterized by the weak dispersion of magnetic anisotropy of the near-surface layers and the high homogeneity of the near-surface local magnetic properties. Furthermore, the microwires exhibit the high plasticity and strength. They are not destroyed even after their full tightening into a knot. The strong influence of tensile stress and torsion on the magnetic properties of the microwires was discovered. The comparison of magneto-field behavior of the studied samples was performed.
