The structure and low-field magnetic properties (i.e. the magnetic susceptibility and its disaccommodation) for the Fe87Zr7B6 and Fe86Zr7B6Cu1 alloys in the amorphous and nanocrystalline states are investigated. It was stated that the replacement of 1 at% iron atoms by Cu atoms in Fe87Zr7B6 leads to the decrease of the crystallization temperature. Moreover, the results obtained indicate that in the nanocrystalline alloys, besides the amorphous matrix and α-Fe grains, the interfacial zone consisting of two components may be distinguished. The volume fraction of the interfacial zone is higher for the nanocrystalline Fe86Zr7B6Cu1 alloy. From studies on the magnetic susceptibility disaccommodation in investigated alloys, it is evident that the relaxation processes occurring in the amorphous phase are the main source of this phenomenon. From the analysis of the isochronal disaccommodation curves (applying a Gaussian distribution of relaxation times) the values of activation energy of the individual processes are found.
