Abstract : The present work is focused on high sensitivity (5000 V/T) transverse coiled GMI transducers manufactured with various magnetic materials, magnetically excited at low frequencies (f < 50 kHz) by an insulated coil which is also used for the measurement of the DC and low frequency magnetic field. The impedance and the sensitivity of different types of ferromagnetic material as nanocrystalline ribbons (Finemet) annealed under longitudinal and transverse magnetic fields, as mumetal ribbons and Mn–Zn thin ferrite core are investigated with respect to the static magnetic field. From these results, the differential magnetic permeability is approximated in order to predict sensitivity behavior in relation to the anisotropy magnetic field and the magnitude and the frequency of current excitation.
