We have studied the soft magnetic behaviors in the nanocrystalline Fe80B12Zr7Cu1 alloy annealed at 450oC and 550oC for 1 hour respectively in a vacuum and examined by means of the magnetoimpedance (MI) effect andthe incremental permeability. The MI effect can be obtained only in good-soft magnetic materials, the improvement ofmagnetic softness by proper thermal treatment was carefully monitored by the MI effect for both annealed samples. Thechanges of the permeability as a function of an external field were also measured to verify the magnetic softness alongwith the MI measurement.
