Abstract
The tunnel states of square-planar bielectron transfer d(n)-d(n)-d(n+1 )-d(n+1) (n = 0-4) clusters are considered. The nature of the ground s pin state is revealed in the limiting case of a strong double exchange . It is shown that the magnetic properties of these systems radically differ from those of clusters with one migrating electron (hole) and t etrameric tetrahedral bielectron transfer clusters.
