On the Ising-heisenberg Model with the Doubly Decorated Network Strucutre I

چکیده
Using an exact mapping transformation method, magnetic properties of a spin-1/2 and spin-1 doubly decorated Ising-Heisenberg model are investigated in detail. By assuming that both interaction parameters are ferromagnetic, we found in addition to an usual ferromagnetic phase another two phases with a nontrivial long-range order.

Unusual Quantum Phase in Exactly Solvable Doubly Decorated Ising-Heisenberg Models
The quantum Heisenberg model belongs to the most intensively studied models in statistical mechanics (see [1] and references therein), since it exhibits very interesting quantum phenomena. However, due to the mathematical complexities related to the quantum nature of the model, only few exact results have been obtained in this field so far. Owing to this fact, the main aim of this work is to in...
متن کاملGround-state phase diagram of geometrically frustrated Ising-Heisenberg model on doubly decorated planar lattices
Frustrated quantum models have attracted a great research interest during the last three decades especially due to their extraordinary diverse ground-state behaviour, which often arises as a result of mutual interplay between the geometric frustration and quantum fluctuations [1]. Despite a considerable effort, the geometric frustration and its effect on magnetic properties of frustrated spin s...
متن کاملReentrant phenomenon in the exactly solvable mixed spin-1/2 and spin-1 Ising-Heisenberg model on diamond-like decorated planar lattices
Ground-state and finite-temperature behaviour of the mixed spin-1/2 and spin-1 Ising-Heisenberg model on decorated planar lattices consisting of inter-connected diamonds is investigated by means of the generalised decoration-iteration mapping transformation. The obtained exact results clearly point out that this model has a rather complex ground state composed of two unusual quantum phases, whi...
متن کاملPhase transitions of geometrically frustrated mixed spin-1/2 and spin-1 Ising-Heisenberg model on diamond-like decorated planar lattices
Phase transitions of the mixed spin-1/2 and spin-1 Ising-Heisenberg model on several decorated planar lattices consisting of interconnected diamonds are investigated within the framework of the generalized decoration-iteration transformation. The main attention is paid to the systematic study of the finite-temperature phase diagrams in dependence on the lattice topology. The critical behaviour ...
متن کاملReentrant transitions of Ising-Heisenberg ferromagnet on a triangular lattice with diamond-like decorations
The mixed spin-1/2 and spin-1 Ising-Heisenberg ferromagnet on the decorated triangular lattice consisting of inter-connected diamonds is investigated within the framework of an exact decoration-iteration mapping transformation. It is shown that the diamond-like decoration by a couple of the Heisenberg spins gives rise to a diverse critical behaviour including reentrant phase transitions with tw...
