Аннотация:The results from a Mössbauer study of 57Fe Mössbauer nuclei in binary phosphide FeP, which has an unusual magnetic structure, are presented. Model decoding of the Mössbauer spectra is performed with allowance for features of the crystal structure of this compound, using data on its spinmodulated magnetic ordering. A proposed model expansion of the spectra allows us to describe consistently Mössbauer data obtained over a wide range of temperatures that includes the magnetic phase transition point. Possible explanations are offered for the low magnitude and spatial anisotropy of hyperfine magnetic field Hhf on 57Fe nuclei.
