Magnetic behaviour of interacting antiferromagnetic nanoparticles

Journal of Physics: Condensed Matter, 2012
Magnetic properties of interacting La(0.2)Ca(0.8)MnO(3) nanoparticles have been investigated. The field-induced transition from antiferromagnetic (AFM) to ferromagnetic (FM) state in the La(0.2)Ca(0.8)MnO(3) bulk has been observed at exceptionally high magnetic fields.

Interaction of light with hexagonal antiferromagnets

Soviet Journal of Low Temperature Physics, 1976
A theoretical study is made of dipole transitions in hexagonal antiferromagnets containing magnetic dipoles with unfilled 3d-shells displaced and undisplaced from the center of inversion. It is shown that, unlike antiferromagnets containing only centrosymmetric magnetic ions, hexagonal antiferromagnets with spin noncollinearity induced by a magnetic ...

The Estimation of Antiferromagnetic Exchange Interactions

Proceedings of the Physical Society, 1961
The estimation of the interaction energies between the magnetic ions in antiferromagnetic crystals is investigated and it is shown that they may be obtained from measurements of the magnetic susceptibility in the paramagnetic phase. High temperature power series expansions of the zero-field susceptibility - well known in connection with ferromagnetic ...

Quantum antiferromagnets with competing interactions

Physica A: Statistical Mechanics and its Applications, 1999
Abstract By applying the method of hierarchy of algebras, we derive exact thermodynamic results of the square 4×4 lattice and of the linear ring of 16 s= 1 2 spins described by an isotropic Heisenberg Hamiltonian. Next-nearest-neighbour interactions are taken into account.

Antiferromagnetism. Theory of Superexchange Interaction

Physical Review, 1950
In this paper the general formalism of Kramers indicating the existence of superexchange interaction has been reduced, under simplifying assumptions, to the point where actual formulas for the interaction can be written down directly in terms of spin operators, with certain exchange and transition integrals as parameters.

Theory of the magnetic properties of Ising antiferromagnets with antiferromagnetic intrasublattice interaction

Soviet Journal of Low Temperature Physics, 1987
The transition in an external magnetic field from the state of a two-sublattice antiferromagnet (AFM) into the paramagnetic (ferromagnetic) state is studied for the example of an exactly solvable model of two coupled chains of Ising spins with competing exchange couplings.
