Large transverse field tunnel splittings in the Fe_8 spin Hamiltonian

Condensed Matter 2009-10-31 v1

Abstract

The spin Hamiltonian that describes the molecular magnet Fe8_8 has biaxial symmetry with mutually perpendicular easy, medium, and hard magnetic axes. Previous calculations of the ground state tunnel splittings in the presence of a magnetic field along the hard axis are extended, and the meaning of the previously discovered oscillation of this splitting is further clarified.
