摘　　要：本文利用Landau-Lifshitz方程求得FeCo基非晶合金薄带在稳恒磁场和交变磁场同时作用下的张量磁导率和平均磁导率,再依据Maxwell方程组求得FeCo基非晶合金薄带的阻抗表达式,进而得到FeCo基非晶合金薄带在稳恒磁场和交变磁场同时作用下的阻抗表达式。Based on the theory model for FeCo-based amorphous alloy, magnetic permeability tensor and average magnetic conductivity for the FeCo-based amorphous alloys on applied stability constant magnetic field and alternating magnetic field are obtained by Landau-Lifshitz equation. Impedance expression of the FeCo-based amorphous alloys is solved by Maxwell equation. Impedance expression of the FeCo-based amorphous alloys on applied stability constant magnetic field and alternating magnetic field is solved in the end.
