| Abstract: | A magnetoimpedance effect is observed in Co80–xNixB20 (x = 4, 6, 8, 10, 12) amorphous metal alloy ribbons when an alternating current at frequencies ranging from 1–3000 kHz is passed
through samples in an external magnetic field. Spectra of the permittivity and optical conductivity of the surface of ribbons
of these alloys are obtained for incident photon energies of 1.0–5.0 eV. The relationships between the magnitude of the magnetoimpedance
effect, and the magnetic properties, electronic structure parameters, and optical characteristics of the amorphous alloy samples
are determined. |
