Transition metal incorporation into 1 mackinawite ( tetragonal FeS )
24 Naturally-occurring mackinawite (tetragonal FeS) with incorporated transition metals 25 is an important precursor to the formation of metal sulfides in ore deposits, but experimental 26 results have not been sufficient to establish clear trends in the structure and stability of the 27 transition-metal-enriched mineral. Using density functional theory with dispersion 28 corrections, we report...
متن کاملSynthesis and Rietveld crystal structure refinement of mackinawite, tetragonal FeS
Mackinawite,tetragonal FeS, has been synthesised by reacting iron with Na2S solutions. A Rietveld structure refinement of X-ray powder diffractipn data, recorded using X-rays monochromated from synchrotron radiationwith a wavelength of 0.6023 A, has been performed. The structure has been refined in the tetragonal sJ'.!lcegroup, P4/nmm, and has the following cell parameters: a = 3.6735(4), c = 5...

Pressure-dependent magnetization and magnetoresistivity studies on tetragonal FeS (mackinawite): revealing its intrinsic metallic character
The transport and magnetic properties of the tetragonal Fe[Formula: see text]S were investigated using magnetoresistivity and magnetization within [Formula: see text] K, [Formula: see text] 70 kOe and [Formula: see text] 3.0 GPa. In addition, room-temperature x-ray diffraction and photoelectron spectroscopy were also applied. In contrast to previously reported nonmetallic character, Fe[Formula:...
