摘要	The work aims at understanding the changes in magnetic properties and the magnetoimpedance (MI) effect for the Fe84.5Zr4B8.5Nb2Cu1 (FZBNC) nanocrystalline alloys with the annealing temperature (T-a) from the microstructure point of view. The as-quenched FZBNC ribbons were annealed in a vacuum condition at selected temperatures for 20 min. The microstructures of the specimens were examined by the x-ray diffraction technique. The bcc alpha-Fe phase is identified from the XRD patterns. The mean grain size of the alpha-Fe phase (D-1) at different annealing temperatures (T-a) was estimated using Scherrer's equation. The results show that D1 for the sample annealed at 575 degrees C is about 20 nm, which is the smallest value among all the samples. Measurements on the MI effect reveal that the FZBNC ribbon annealed at 575 degrees C exhibits the most drastic MI ratio of 756% at 600 kHz accompanied by the field sensitivity of 108% Oe(-1), while a large MI effect is not observed in the sample annealed at other temperatures. The origin of the excellent MI effect is investigated in this paper.
