Zusammenfassung:Magnetic properties of planar molecular magnets have been investigated by Mössbauer spectroscopy. A significant increase in the linewidth of the magnetic hyperfine structure with an increase in temperature is observed. A fluctuation model of magnetism for magnets lacking long-range magnetic order is proposed. This model describes the magnetic field distributions in these magnets in a wide temperature range with the use of a fixed set of coupling constants.
