Abstract
The magneto-impedance (MI) effect in amorphous and current annealed Fe{sub 73.5}Cu{sub 1}Nb{sub 3}Si{sub 13.5}B{sub 9} wires has been measured to investigate the influence of DC annealing, high-current-density electropulsing annealing and tensile stress on it. The results show that the MI of DC annealed sample exhibits sharp maximum at H{sub ex}=H{sub k}. Maximum MI ratio of 60% is observed in sample of high-current-density electropulsing annealed under applied tensile stress.
