Magnetic hyperfine fields of Fe90Zr7B3 Nanoperm nanocrystalline alloy are characterized by Fe-57 Mossbauer spectrometry and Fe-57 NMR as well as by magnetic force microscopy. Fe-57 NMR enables to distinguish a broad signal of iron atoms located in a residual amorphous matrix from a narrow one which belongs to Fe in nanograins. The former coincides with the distribution of hyperfine fields obtained from Fe-57 Mossbauer spectroscopy. In addition, it is possible to make a distinction between NMR signals of the Fe nanograins located in magnetic domains from that of the nanograins positioned in domain walls. This is confirmed by magnetic force microscopy where appearance of maze-domains is observed.
