“…Off-diagonal magnetoimpedance has been studied in detail for Co-based amorphous wires 12−17 and multilayered films. 18,19 It has been demonstrated that the off-diagonal magnetoimpedance may be preferable for sensor applications since it generates a linear voltage response with enhanced field sensitivity. However, up to now the effect has not been investigated in amorphous ribbons.…”

The off-diagonal magnetoimpedance in field-annealed CoFeSiB amorphous ribbons was measured in the low-frequency range using a pickup coil wound around the sample. The asymmetric two-peak behavior of the field dependence of the off-diagonal impedance was observed. The asymmetry is attributed to the formation of a hard magnetic crystalline phase at the ribbon surface. The experimental results are interpreted in terms of the surface impedance tensor. It is assumed that the ribbon consists of an inner amorphous region and surface crystalline layers. The coupling between the crystalline and amorphous phases is described through an effective bias field. A qualitative agreement between the calculated dependences and experimental data is demonstrated. The results obtained may be useful for development of weak magnetic-field sensors.
