Özet
Magneto impedance (MI) and hysteresis loops in amorphous (Co0.9Fe0.05Ni0.05)(75)Si15B10 ribbons were measured to investigate the influence of current and field annealing. The results indicated that a transverse anisotropy was induced by both the magnetic field and current annealing methods. Using both techniques we succeeded in inducing the same magnitude of uniaxial anisotropy, K-u. It was observed that current annealed samples showed a larger MI effect. Since both samples have the same K-u, the difference in the magnitude of MI was explained by the domain structure. A positive MI effect, as large as 62%, was found in the 60 min current annealed sample at a 1 MHz driving frequency. (c) 2005 Elsevier B.V. All rights reserved.
