The frequency dependence of magnetoimpedance (MI) effect in amorphous Fe_(78)B₁₃Si_9 alloy has been obtained. Magnetoimpedance (MI) effect is a high-frequency phenomenon, which describes the changes of impedance in any ferromagnetic sample, when a magnetic field is applied on it. MIR (Magnetoimpedance ratios) is defined as Δ Z/Z ≡ [Z(0)/Z(Hs)]-1 where Hs is the saturating field along the long side of the sample. The MIR of the samples annealed in vacuum has been decreased normally except that the sample annealed at 5㎒ has been reached as much as 58%.
