tThe effect of addition of Co and V on the hyperfine parameters of amorphous as well as nanocrystalline Finemet-type alloys has been studied by means of transmission Mössbauer spectrometry. It was
stated that these elements infiltrate into crystalline grains in the course of crystallization,
what causes alteration in structure. Different evolution of magnetic hyperfine field is reported in both cases and analyzed. In the series of alloys substituted by vanadium, the substantial
paramagnetic component attributed to iron-poor regions in the amorphous remainder was found.
