Reference approach in theory of pseudospin systems
R. R. Levitskii, S. I. Sorokov, O. R. Baran
For theoretical description of pseudospin systems with essential short-range and long-range interactions we use the method based on calculations of the free energy functional with…
Pair correlation functions of the Ising type model with spin 1 within two-particle cluster approximation
O. R. Baran, R. R. Levitskii
The Blume-Emery-Griffiths model on hypercubic lattices within the two-particle cluster approximation is investigated. The expressions for the pair correlation functions in …
Phase diagrams of spin-1 Ising model with bilinear and quadrupolar interactions under magnetic field. Two-particle cluster approximation
R. R. Levitskii, O. R. Barana, B. M. Lisnii
The spin-1 Ising model with bilinear and quadrupolar short-range interactions under magnetic field is investigated within the two-particle cluster approximation. It is shown that f…
Influence of transverse field on the spin-3/2 Blume-Capel model on rectangular lattice
O. Baran, R. Levitskii
Transverse field effect on thermodynamic properties of the spin-3/2 Blume-Capel model on rectangular lattice in which the interactions in perpendicular directions differ in signs i…
Phase diagrams of spin-3/2 Blume-Capel model on rectangular lattice under longitudinal magnetic field
O. Baran, R. Levitskii
The spin-3/2 Blume-Capel model on a rectangular lattice with the ferromagnetic bilinear short-range interaction in one direction and the anti-ferromagnetic one $…
