Powdered troilite (FeS), extracted from the Cape York IIIA octahedrite meteorite, was investigated employing in-field 57Fe Mössbauer spectroscopy. The study identified a typical behavior of polycrystalline antiferromagnetic material under external magnetic fields. The in-field evolution of the 57Fe Mössbauer spectra showed that the spin-flop transition in the FeS system occurs at a field higher than 5 T.
