Quantum analogue of the spin-flop transition for a spin pair
B. A. Ivanov, V. E. Kireev
Quantum (step-like) magnetization curves are studies for a spin pair with antiferromagnetic coupling in the presence of a magnetic field parallel to the easy axis of the magnetic a…

Interference of Instanton Trajectories in Quantum Tunneling for Small Particles of Real Antiferromagnets
B. A. Ivanov, V. E. Kireev
For a two-sublattice antiferromagnet the Lagrangian is constructed taking into account Berry phase whose form is matched to the quantum-mechanical Heisenberg Hamiltonian. Tunnel ef…
