FIG. 1.

The evolution of the unit magnetization vector components () and () in the absence of the dc bias current,  = 0, within the range of positive (a) and negative (b) axial magnetic fields. The applied magnetic field decreases from  = 3.0 Oe up to  = −3.0 Oe.

FIG. 2.

The dependence of the unit magnetization vector components at the surface of the metallic core of the wire with helical anisotropy on (a) the sign of the off-diagonal residual stress component ; (b) the amplitude of the dc bias current. The external magnetic field is reduced from  = 5 Oe to − 5 Oe.

FIG. 3.

The dependence of the diagonal GMI component of amorphous microwire with helical anisotropy (a) on the frequency and (b) on the magnetic damping constant. The applied magnetic field is reduced from  = 7.5 Oe to − 7.5 Oe.

FIG. 4.

The dependence of the diagonal (a) and off-diagonal (b) GMI components of amorphous wire with helical anisotropy on the amplitude of the dc bias current.

Image of FIG. 5.
FIG. 5.

The reduced diagonal GMI component of Co-rich amorphous microwire at a frequency  = 4 MHz measured at different bias currents (symbols). The corresponding theoretical curves are shown by solid lines.

Image of FIG. 6.
FIG. 6.

The reduced off-diagonal GMI component (a) in the absence of the bias current,  = 0 and (b) for various bias currents. Symbols represent the experimental data; the corresponding theoretical curves are shown by solid lines.
