Overview

We produced NiFeMo ribbons by electrodeposition technique under applied currents ranging from 40 to 240 mA. The SEM analysis showed a uniform and crack-free coating. Then, we measured the transverse and longitudinal magnetoimpedance of ribbons. We also obtained the hysteresis loops of the ribbons by means of magnetooptical Kerr effect to investigate their magnetic properties. The result showed that the increase in deposition current density caused a decline in the magnetic softness of the ribbons so that some of the ribbons exhibited an exchange spring effect. The magnetic hardening also caused a reduction in the magnetoimpedance response. We also theoretically calculated the susceptibility of a ribbon by considering the random magnetic anisotropy. The multi-peak behavior of susceptibility is in agreement with the multi-peak behavior of magnetoimpedance.
