Macroscopic Quantum Coherence in Small Antiferromagnetic Particle and the Quantum Interference Effects
Y. -H. Nie, Y. -B. Zhang, J. -Q. Liang +2
Starting from the Hamiltonian operator of the noncompensated two-sublattice model of a small antiferromagnetic particle, we derive the effective Lagrangian of a biaxial antiferroma…
Crossover from thermal hopping to quantum tunneling in Mn_{12}Ac
S. P. Kou, J. Q. Liang, Y. B. Zhang +2
The crossover from thermal hopping to quantum tunneling is studied. We show that the decay rate with dissipation can accurately be determined near the crossover temperature. Be…
Quantum-Classical Phase Transition of Escape rate in Biaxial Spin Particles
Y. -B. Zhang, J. -Q. Liang, H. J. W. Muller-Kirsten +3
The escape rates of the biaxial single domain spin particles with and without an applied magnetic field are investigated. Using the strict potential field description of spin syste…
