Self-organization of topological defects for a triangular-lattice magnetic dots array subject to a perpendicular magnetic field
R. Khymyn, V. Kireev, B. Ivanov
The regular array of magnetic particles (magnetic dots) of the form of a two-dimensional triangular lattice in the presence of external magnetic field demonstrates complicated magn…
Vortex ground state for small arrays of magnetic particles with dipole coupling
S. A. Dzian, A. Yu. Galkin, B. A. Ivanov +2
We show that a magnetic vortex is the ground state of an array of magnetic particles shaped as a hexagonal fragment of a triangular lattice, even for an small number of particles i…
Ground states and magnetization process for an triangular lattice array of magnetic dots with perpendicular anisotropy
V. E. Kireev, R. S. Khymyn, B. A. Ivanov +1
We analyzed the ground state of the array of magnetic particles (magnetic dots) which form a two-dimensional triangular lattice, and magnetic moment of which is perpendicular to th…
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…
Macroscopic Quantum Tunneling in Small Antiferromagnetic Particles: Effects of a Strong Magnetic Field
B. A. Ivanov, V. E. Kireev
We consider an effect of a strong magnetic field on the ground state and macroscopic coherent tunneling in small antiferromagnetic particles with uniaxial and biaxial single-ion an…
