Magnetic structure of greigite (Fe 3 S 4 ) probed by neutron powder diffraction and polarized neutron diffraction
We have investigated greigite (Fe3S4 using a combination of neutron powder diffraction and polarized neutron diffraction to give the first unambiguous assignment of its magnetic structure. Our results confirm that greigite has a collinear ferrimagnetic structure with antiferromagnetic coupling between the tetrahedral (A) and octahedral (B) sites. Our analysis also indicates that greigite does not have a significant vacancy concentration or spin canting. High-resolution neutron powder...[Show more]
