“…(7) The stable geometric parameters of the Co 69 Fe 4 Cr 4 Si 12 B 11 microwires along their lengths cause the slight dispersion of magnetic anisotropy of the near-surface layers. As a result, the thick microwires are characterized the high homogeneity of the near-surface local magnetic properties (8) The discovered properties of the thick Co 69 Fe 4 Cr 4 Si 12 B 11 amorphous microwire make these materials promising for practical applications. In particular, thick high-strength Co-rich microwires can find applications at manufacturing of constructional and functional materials, and also composites, containing microwires as a power element.…”

“…Amorphous materials, prepared as microwires, deserve special attention. In particular, the revealed unique magnetic properties of amorphous microwires were caused their wide application in practice for manufacturing high sensitive sensors of magnetic fields, stresses, low pressures, strains, etc., and also new types of coding devices [4][5][6][7][8][9][10][11][12].…”

The structural and magnetic properties of as-cast and annealed Co-rich microwires in a glass shell with the diameter of D = 125 μm and the diameter of the amorphous metallic core of d = 50-90 μm, produced by the modernized Ulitovsky-Taylor method, have been investigated. The saturation field H S and the coercive force H C of the samples were found to depend on annealing temperature. The near-surface values of H S and H C were discovered to be larger than the bulk ones. The obtained experimental data were explained by the structural features of the microwires under study.

A giant magnetoimpedance (GMI) magnetic sensor is designed in the present work. Differing from the previously reported sensors, a couple of permanent magnets are applied to provide a bias magnetic field for the sensor probe which consists of commercial amorphous ribbon. A negative feedback-coil is adopted to improve the linearity of the sensor output. The sensor shows sensitivity of 1041mV/Oe in the range of ±1Oe, measurement precision of less than 0.11% at room temperature and good thermal stability in the temperature region between -20 and 30 .
