| Abstract: | The Mössbauer effect has been studied in SrLnFeO4 compounds (Ln=La, Pr, Nd, Sm, Eu, Gd) with K2NiF4 structure in the temperature range between 80K and 459K. The N?el temperture was determined to be 330±5K for SrLaFeO4, 250±5K for SrPrFeO4, 270±5K for SrNdFeO4 and 400±10K for SrSmFeO4. The results of the combined magnetic and quadrupole interactions indicated that the direction of internal magnetic field is perpendicular to the Z-axis of the EFG tensor and parallel to the c-axis of the crystal structure. |
