XMCD at Fe L2,3 edges, Fe and S K edges on Fe7S8

Résumé

Pyrrhotite (Fe7S8) is a natural iron sulphide that can participate in rock magnetisation. Its elec- tronic structure is not yet surely described. X-ray magnetic circular dichroism (XMCD) at Fe L2,3 edges on Fe7S8, coupled with multiplet calculations, shows that iron is present only as Fe2+ in this magnetic iron sulphide. It reveals a strong magnetic orbital moment. XMCD at Fe and S K edges shows the quite strong Fe7S8:
