Structural and Magnetic Properties of Fe73,5Si13,5B9Nb3Cu1 Microwires Produced by Modernized Ulitovsky-Taylor Method

Results of the investigation of the mechanical, elastic and magnetic characteristics of the “thick” Fe73,5Si13,5B9Nb3Cu1 amorphous microwires, produced by the modernized Ulitovsky–Taylor method, are presented. The cores of the Fe73,5Si13,5B9Nb3Cu1 microwires were found to have the stable geometric parameters along their length and the smooth (almost without defects) surface. The microwires are characterized by the high plasticity and the high strength. The stable geometric parameters of the Fe73,5Si13,5B9Nb3Cu1 microwires along their lengths cause the slight dispersion of magnetic anisotropy of the near-surface layers. As a result, the microwires exhibit the high homogeneity of the near-surface local magnetic properties. The strong influence of the stretching and torsion tensions on the remagnetization signal of the microwires was discovered.
