Spin and Orbital Order in Itinerant Ferromagnets

  • P. Fazekas
Article

Abstract

The long-standing problem of the effect of correlations on the ferromagnetism of transition metals is apparently nearing solution. The ferromagnetism of transition metal compounds, for instance doped manganites, poses a new question: is there some kind of orbital order coexisting with itinerant ferromagnetism? The ideas and techniques introduced by Gutzwiller should be of use again.
