This work is devoted to the study of the magnetic domain structure (DS) in heterogeneous nanocrystalline alloys (R,Zr)(Co,Cu,Fe)z (R = Sm; z = 6.0-6.7). The methods of optical and atomic force microscopy were used to determine the parameters of micro- and nanostructure («cells») of the alloys. The method of magnetic force microscopy was used to obtain the images of the domain structure of these samples. A comparative analysis of the parameters of the domain and "cellular" structure of the alloys was performed. The dependence of the DS parameters on the parameters of the nanostructure is shown. The mixed mechanism of the magnetic reversal realized in these alloys is discussed.

The Domain Structure of Die-Upset Anisotropic Magnet Based On Nd-(Fe, Co)-B Alloy The measurements of the recoil curves for the die-upset Nd-(Fe, Co)-B based magnets from different points on the magnetization and demagnetization curves have been carried out by means of the LakeShore vibrating sample magnetometer in an applied magnetic fields up to 2 T. From the recoil curves the so-called Wohlfarth's remanence relationship has been derived. From this it was deduced that the magnetic interaction existing between the magnet grains has a dipolar nature. The existence of the magnetic interaction has been confirmed by magnetic domain observations by using the magnetic force microscopy (MFM). In the area of interaction domains there is the fine scale magnetic contrast resulting from the dipolar interaction between neighboring grains.
