Abstract
The magnetism of Fe and Ni is investigated by a cluster theory with two novel features: (i) The coupling of magnetic moments formed by clusters (described by a local band theory) is determined, thus incorporating short-range order as well as collective modes. (ii) The clusters are coupled by source and sink terms describing transport processes. The results indicate that Fe is closer to a local moment system, whereas Ni seems to be a prototype for a local band theory.Keywords
