Magnetization plateaus in the Ising limit of the multiple-spin exchange model on plaquette chain

We consider the Ising spin system, which stems out from the corresponding Multiple-spin exchange (MSE) Hamiltonian, on the special one--dimensional lattice, diamond-plaquette chain. Using the technique e of transfer-matrix we obtain the exact express

An exact solution on the ferromagnetic Face-Cubic spin model on a Bethe lattice

Autor: Ohanyan, V. R., Ananikyan, L. N., Ananikian, N. S.

Publikováno v: Physica A 377, 501-513 (2007)

The lattice spin model with $Q$--component discrete spin variables restricted to have orientations orthogonal to the faces of $Q$-dimensional hypercube is considered on the Bethe lattice, the recursive graph which contains no cycles. The partition fu

Magnetization plateaus in the ferromagnetic-ferromagnetic-antiferromagnetic Ising chain

Autor: Ohanyan, V. R., Ananikian, N. S.

Publikováno v: Phys. Lett. A 307, 76 (2003)

The Ising chain consisting of the antiferromagneticaly coupled ferromagnetic trimer is considered in the external magnetic field. In the framework of the transfer-matrix formalism the thermodynamics of the system is described. The magnetization per s
