Overview

abstract

• The onset of noncollinear magnetism in small FeN clusters is investigated by using a rotational invariant tight-binding Hamiltonian. The ground-state local magnetic moments, magnetic order and average magnetic moments are calculated as a function of the Coulomb exchange integral J. Representative results for Fe3 and Fe5 show that the noncollinear magnetic solutions are the most stable. A variety of qualitatively different self-consistent solutions is obtained as a function of J. This includes magnetic solutions with collinear and noncollinear spin arrangements. Our calculations are compared with previous density-functional results. Extensions and limitations of our work are also pointed out. © 2009 EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg.
