Spin-Glass-Like Behavior and Concentration Phase Transitions in Model of Monolayer Two-Sublattice Magnetics

Abstract:

Two-sublattice magnets with competing direct exchange interactions can exhibit spin-glass properties. It is shown that the Ising model on a 2D lattice with z = 8 nearest neighbors takes place divergence between the ZFC and FC magnetization curves. It was shown, that a weak antiferromagnetic interaction between ferromagnetically ordered sublattices with approximately similar values of the magnetic moments in the sites can lead to very complex magnetic properties. Theoretical magnetic phase diagram for the structures with random dilution was built.
