Geometric-phase interference in a Mn_{12} single-molecule magnet with four-fold rotational symmetry
S. T. Adams, E. H. da Silva Neto, S. Datta +6
We study the magnetic relaxation rate Gamma of the single-molecule magnet Mn_{12}-tBuAc as a function of magnetic field component H_T transverse to the molecule's easy axis. When t…
Geometric-Phase-Effect Tunnel-Splitting Oscillations in Single-Molecule Magnets with Fourth-Order Anisotropy Induced by Orthorhombic Distortion
M. S. Foss-Feig, Jonathan R. Friedman
We analyze the interference between tunneling paths that occurs for a spin system with both fourth-order and second-order transverse anisotropy. Using an instanton approach, we fin…
Radiation- and Phonon-Bottleneck-Induced Tunneling in the Fe8 Single-Molecule Magnet
M. Bal, Jonathan R. Friedman, W. Chen +4
We measure magnetization changes in a single crystal of the single-molecule magnet Fe8 when exposed to intense, short (<20 s) pulses of microwave radiation resonant with the m =…
Measurement of Magnetization Dynamics in Single-Molecule Magnets Induced by Pulsed Millimeter-Wave Radiation
M. Bal, Jonathan R. Friedman, M. T. Tuominen +2
We describe an experiment aimed at measuring the spin dynamics of the Fe8 single-molecule magnet in the presence of pulsed microwave radiation. In earlier work, heating was observe…
Photon-Induced Magnetization Changes in Single-Molecule Magnets
M. Bal, Jonathan R. Friedman, E. M. Rumberger +6
Microwave radiation applied to single-molecule magnets can induce large magnetization changes when the radiation is resonant with transitions between spin levels. These changes are…
Non-equilibrium Magnetization Dynamics in the Fe_8 Single-Molecule Magnet Induced by High-Intensity Microwave Radiation
M. Bal, Jonathan R. Friedman, Y. Suzuki +6
Resonant microwave radiation applied to a single crystal of the molecular magnet Fe_8 induces dramatic changes in the sample's magnetization. Transitions between excited states are…
