Abstract

The asymmetry of axial and off-diagonal impedance was investigated in as-quenched and field-annealed amorphous Co₆₇ Fe₄ Cr₇ Si₈ B₁₄ ribbons. The asymmetry of impedance characteristics can be controlled by DC bias current and torque. When an appropriate uniaxial anisotropy is superimposed very high field sensitivity (about 3000%/Oe) can be obtained. The proposed theoretical model well explains the observed behavior.
