Synthesis of cobalt grown from Co-S eutectic in high magnetic fields
Samples of Co were grown directly in the ferromagnetic state under equilibrium conditions using a cobalt sulfide flux. Magnetic fields up to 9 T were applied during growth, and isolated Co products exhibit progressively elongated morphologies, from cubes to rectangular rods to needle-like tendrils with poorly-defined facets. The degree of elongation of the major axis was found to correlate with magnetic field direction, strength, and gradient. Two-dimensional X-ray diffraction data indicate some level of polycrystalline-like samples, and quantitative analyses (Le Bail and Rietveld) of the one-dimensional data confirm the presence of hcp and fcc phases. The magnetic responses indicate a partial alignment of the magnetic easy-axis of the hcp phase along the magnetic field present during growth.

Materials Data on Co3S4 by Materials Project
Co3S4 is Hausmannite structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. there are two inequivalent Co+2.67+ sites. In the first Co+2.67+ site, Co+2.67+ is bonded to six equivalent S2- atoms to form CoS6 octahedra that share corners with six equivalent CoS4 tetrahedra and edges with six equivalent CoS6 octahedra. All Co–S bond lengths are 2.26 Å. In the second Co+2.67+ site, Co+2.67+ is bonded to four equivalent S2- atoms to form corner-sharing CoS4 tetrahedra. The corner-sharing octahedral tilt angles are 57°. All Co–S bond lengths are 2.13 Å. S2- is bonded in a distorted rectangular see-saw-like geometry to four Co+2.67+ atoms.
