Enigmatic X-ray magnetic circular dichroism in Greigite (Fe3S4)

Chang, Liao; Pattrick, Richard A.D.; van der Laan, Gerrit; Coker, Victoria S.; Roberts, Andrew

Description

Greigite (Fe3S4), a widely occurring iron thiospinel, was investigated using soft X-ray absorption spectroscopy (XAS) and X-ray magnetic circular dichroism (XMCD). XAS and XMCD spectra were recorded at the Fe L2,3 edges for pure synthetic and natural greigite samples. At the Fe L3 edge, the XAS spectra reveal two main absorption peaks at 707.2 and 708.6 eV, which are interpreted to originate from greigite and an oxidized surface layer on greigite crystals. The XMCD spectra, which are dominated...[Show more]
