Abstract

The dependence of magnetization dynamics and magneto-impedance effect in positively magnetostrictive Fe_77.5Si_7.5B ₁₅ amorphous wires on annealing conditions was studied. The observed MI ratio of the annealed samples was as much as 36% and optimum annealing conditions were suggested. The locus of the magnetization vector of the annealed wire indicated that the circumferential magnetization proceeded easily in the annealed wire. It was also suggested that the effect of oxidation should be considered for samples annealed in air
