Abstract
The spin Hamiltonian that describes the molecular magnet Fee has biaxial sy mmetry with mutually perpendicular easy, medium, and hard magnetic axes. Pr evious calculations of the ground-state tunnel splittings in the presence o f a magnetic field along the hard axis are extended, and the meaning of the previously discovered oscillation of this splitting is further clarified.
