Partial spin reversal in magnetic deflagration
S. Vélez, P. Subedi, F. Macià +6
The reversal of spins in a magnetic material as they relax toward equilibrium is accompanied by the release of Zeeman energy which can lead to accelerated spin relaxation and the f…
Realization of random-field dipolar Ising ferromagnetism in a molecular magnet
Bo Wen, P. Subedi, Lin Bo +5
The longitudinal magnetic susceptibility of single crystals of the molecular magnet Mn-acetate obeys a Curie-Weiss law, indicating a transition to a ferromagnetic phase due…
Symmetry of Magnetic Quantum Tunneling in the Single-Molecule Magnet Mn12-Acetate
E. del Barco, A. D. Kent, S. Hill +6
The symmetry of magnetic quantum tunneling (MQT) in the single molecule magnet Mn12-acetate has been determined by sensitive low-temperature magnetic measurements in the pure quant…
Symmetry of Magnetic Quantum Tunneling in Single Molecule Magnet Mn12-acetate
E. del Barco, A. D. Kent, E. M. Rumberger +2
The symmetry of magnetic quantum tunneling has been studied in the prototype single molecule magnet Mn-acetate using a micro-Hall effect magnetometer and superconducting hig…
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…
More Evidence for a Distribution of Tunnel Splittings in Mn-acetate
K. M. Mertes, Yoko Suzuki, M. P. Sarachik +6
In magnetic fields applied parallel to the anisotropy axis, the magnetization of Mn has been measured in response to a field that is swept back and forth across the resonanc…
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…
