Abstract

The giant magnetoimpedance (GMI) is studied as function of annealing-field angle θ_k in Co₆₆ Fe₄NiB₁₄Si₁₅ ribbon with respect to transverse direction. The GMI profile at 10 MHz shows two peaks located at negative and positive external field H. The interval between two peaks, about 2.1 Oe for θ_k= 0°, slightly increases with θ_k up to θ_k = 30° and then decreases down to 1.0 Oe for θ_k = 90°. However, two peaks are asymmetric and hysteresis exists during cyclic magnetization. The asymmetry ratio, fractional difference of two peaks, is maximum about 2% for θ_k = 10° and its sign is reversed from θ_k = 40°.
