Quantum Coherence in Fe8 Molecular Nanomagnets
E. del Barco, N. Vernier, J. M. Hernandez +4
We report observation of coherent quantum oscilations in spin-10 Fe8 molecular clusters. The powder of magnetically oriented Fe8 crystallites was placed inside a resonator, in a dc…
Quantum-Classical Escape-Rate Transition of a Biaxial Spin System with a Longitudinal Field: a Perturbative Approach
D. A. Garanin, E. M. Chudnovsky
The quantum-classical transition of the escape rate of the spin model \cal H= -DS_z^2 - H_zS_z + B S_x^2 is investigated by a perturbative approach with respect to B [D. A. Garanin…
Quantum-Classical Transition of the Escape Rate of a Uniaxial Spin System in an Arbitrarily Directed Field
D. A. Garanin, X. Martinez Hidalgo, E. M. Chudnovsky
The escape rate Γof the large-spin model described by the Hamiltonian H = -DS_z^2 - H_zS_z - H_xS_x is investigated with the help of the mapping onto a particle moving in a double-…
Thermally Activated Resonant Magnetization Tunneling in Molecular Magnets: Mn_12Ac and others
D. A. Garanin, E. M. Chudnovsky
The dynamical theory of thermally activated resonant magnetization tunneling in uniaxially anisotropic magnetic molecules such as Mn_12Ac (S=10) is developed.The observed slow dyna…
Structure of an Elastic Lattice Pinned by Hopping Defects
Eugene M. Chudnovsky
The translational order in a three-dimensional lattice pinned by hopping defects is studied. It is suggested that the equilibrium state of the lattice crosses from a glass to a cry…
