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…

Periodic Instanton and Phase Transition in Quantum Tunneling of Spin Systems
Y. -B. Zhang, Y. -H. Nie, S. -P. Kou +3
The quantum-classical transitions of the escape rates in a uniaxial spin model relevant to the molecular magnet MnAc and a biaxial anisotropic ferromagnetic particle are inv…
