Abstract

A new frequency-modulation (FM)-type MI sensor utilizing Fe ₇₃Cu₁Nb_1.5V₂Si_13.5B ₉ ribbons has been developed. A maximal sensitivity of 527%/kA/m in the oscillation frequency versus external dc external magnetic field was obtained. The sensitivity and the linear range of the sensor can be controlled by changing the transverse magnetic anisotropy, which is induced by longitudinal tensile stress annealing. It has promising applications in weak magnetic field measurement and magnet navigation owing to its high sensitivity.
