Gamma-resonance studies of ultrathin magnetic fields on 57Fe nuclei in multicomponent compounds of iron with metals and a neodymium magnet of the Nd2Fe14B composition have been carried out. It is shown that ultrathin magnetic fields Hn are observed on 57Fe iron nuclei in all studied compounds, the largest of which falls on 57Fe nuclei in Ni45Fe45B10, which significantly exceeds the 57Fe field in a neodymium magnet, which also has the highest magnetic induction among known permanent magnets. A qualitative analysis of the mechanism of formation of ultrathin magnetic fields on iron nuclei in the studied compounds is proposed. Keywords: magnetism, permanent magnets, metals, gamma resonance, neodymium magnet, nuclear spectrum, ultrathin magnetic fields, isomer shift.
