Abstract
A tavorite-structured LiFePO4F was synthesized using a two-step solid-state reaction as pure single phase without the impurity phase. Rietveld refinement using X-ray diffraction showed that the crystal structure was triclinic with space group P \(\overline{1 }\). Temperature dependence magnetic susceptibility curve indicated an antiferromagnetic structure with a magnetic ordering, Néel temperature (TN), of 73 K. From inverse magnetic susceptibility curve, the Curie–Weiss temperature was fitted to − 120 K. The spin reorientation temperature (TS) was determined to be 31 K by vibrating sample magnetometer and Mössbauer spectrometer. The Mössbauer spectra above TN was analyzed two doublets, indicating the Fe1(A) and Fe2(B) sites in FeF2O4 octahedra, while below TN, the spectra were fitted with sextet of two sets. The slope change of magnetic hyperfine field and electric quadrupole splitting suggested contribution to the magnetic properties by spin–orbit coupling. The isomer shift for all temperatures indicates that the Fe charge state was Fe3+ ion state for both Fe1(A) and Fe2(B).
