Y. Takemura et al., DEPENDENCE OF MAGNETIZATION DYNAMICS AND MAGNETO-IMPEDANCE EFFECT IN FESIB AMORPHOUS WIRE ON ANNEALING CONDITIONS, IEEE transactions on magnetics, 32(5), 1996, pp. 4947-4949
Dependence of magnetization dynamics and magneto-impedance effect in p
ositively magnetostrictive Fe77.5Si7.5B15 amorphous wires on annealing
conditions was studied. The observed MI ratio of the annealed samples
was as much as 36% and the optimum annealing conditions were suggeste
d. The locus of magnetization vector of the annealed wire indicated th
at the circumferential magnetization was easily proceeded in the annea
led wire. It was also suggested that the effect of oxidation should be
considered for the samples annealed in air.
