Nanocrystalline alloys of Fe86.5Zr6.5Cu1B6 and Fe40.5Co40.5Nb7B12 were measured by the Mössbauer spectrometry in the weak external magnetic field of 0.5 T. In these conditions the most sensitive parameters of the Mössbauer spectra are the intensities of 2nd and 5th lines and the values of internal magnetic field showed rather small changes. The amorphous part of the sample is more sensitive to the external influence than the nanocrystalline one. The behavior of nanocrystalline alloys under weak external magnetic field was analyzed within influence of interparticles interactions on the magnetic parameters.
