Abstract
We clarify the existence of several magnetization plateaux for the kagome antiferromagnetic Heisenberg model in a magnetic field. Using approximate or exact localized magnon eigenstates, we are able to describe in a similar manner the plateau states that occur for magnetization per site , , and of the saturation value. These results are confirmed using large-scale Exact Diagonalization on lattices up to 63 sites.
