Abstract

The magnetic molecule Fe₈ has been predicted and observed to have a rich pattern of degeneracies in its spectrum as an external magnetic field is varied. These degeneracies have now been recognized to be diabolical points. This paper analyzes the diabolicity and all essential properties of this system using elementary perturbation theory. A variety of arguments is given to suggest that an earlier semiclassical result for a subset of these points may be exactly true for arbitrary spin.
