Tunneling and inversion symmetry in single-molecule magnets: the case of the Mn12 wheel molecule
E. del Barco, S. Hill, C. C. Beedle +3
We present a detailed study of the influence of various interactions on the spin quantum tunneling in a Mn12 wheel molecule. The effects of single-ion and exchange (spin-orbit) ani…
Quantum dynamics of exchange biased Single Molecule Magnets
W. Wernsdorfer, N. Aliaga-Alcalde, R. Tiron +2
We present a new family of exchange biased Single Molecule Magnets in which antiferromagnetic coupling between the two components results in quantum behaviour different from that o…
Two-body tunnel transitions in a Mn4 Single-Molecule Magnet
W. Wernsdorfer, S. Bhaduri, R. Tiron +2
The one-body tunnel picture of single-molecule magnets (SMMs) is not always sufficient to explain the measured tunnel transitions. An improvement to the picture is proposed by incl…
Tunneling Splittings in Mn12-Acetate Single Crystals
E. del Barco, A. D. Kent, E. M. Rumberger +2
A Landau-Zener multi-crossing method has been used to investigate the tunnel splittings in high quality Mn-acetate single crystals in the pure quantum relaxation regime and…
Spin-spin cross-relaxation in single-molecule magnets
W. Wernsdorfer, S. Bhaduri, R. Tiron +2
It is shown that dipolar and weak superexchange interactions between the spin systems of single-molecule magnets (SMM) play an important role in the relaxation of magnetization. Th…
Abrupt Transition between Thermally-Activated Relaxation and Quantum Tunneling in a Molecular Magnet
K. M. Mertes, Y. Zhong, M. P. Sarachik +5
We report Hall sensor measurements of the magnetic relaxation of Mn acetate as a function of magnetic field applied along the easy axis of magnetization. Data taken at a ser…
