Greigite Fe3S4 is one of the two natural magnetic iron sulphides. Its formula and structure make it the sulphide equivalent of magnetite Fe3O4, leading to frequent confusions between these two spinelles in paleomagnetic studies and possible wrong interpretation of some paleaomagnetization measurements.

Microwave Investigation of Greigite Nanoparticles Magnetic Properties
2020 IEEE Ukrainian Microwave Week (UkrMW), 2020We experimentally investigated the nanoparticles of iron sulfide Fe 3 S 4 , known as the mineral greigite, with the mean crystallite size of ~30 and ~120 nm, which have been prepared via hydrothermal synthesis by using two different surfactants (oleic acid and cetyltrimethylammonium bromide).

Magnetic properties of nanotextured greigite.
2020<p>Greigite (Fe<sub>3</sub>S<sub>4</sub>) is a ferrimagnetic mineral widespread in sedimentary environments, commonly found in lacustrine and marine sediments that records ancient geomagnetic field variations and environmental processes.

Mössbauer effect study of natural greigite
Hyperfine Interactions, 1992The hyperline parameters of relatively well crystallized grelgite (Fe3S4) have been determined by Mossbauer spectroscopy on a natural greigite-smythite sample. Applied-field measurements confirm the ferrimagnetic behavior. Saturation values of the magnetic hyperfine fields are 31.8 and 33.0 T for the tetrahedral and octahedral Fe respectively.

Nanocomposite Pyrite–Greigite Reactivity toward Se(IV)/Se(VI)
Environmental Science & Technology, 2012A nanopyrite/greigite composite was synthesized by reacting FeCl(3) and NaHS in a ratio of 1:2 (Wei et al. 1996). Following this procedure, the obtained solid phases consisted of 30-50 nm sized particles containing 28% of greigite (Fe(2+)Fe(3+)(2)S(4)) and 72% pyrite (FeS(2)).

Magnetic, FMR and mössbauer studies of nanocrystalline greigite
Journal of Alloys and Compounds, 2021Abstract Iron sulphide Fe3S4, known as the mineral greigite, has been prepared in two distinct nanocrystalline forms with the mean crystallite size of dXRD ≈ 30 and 80 nm via hydrothermal synthesis by using two different surfactants (oleic acid and cetyltrimethylammonium bromide).
