چکیده
We investigated the dynamic phase transitions (DPTs) in mixed spin (2, 5/2) Blume-Emery Griffiths model with repulsive biquadratic interaction presence of a time-varying magnetic field. used path probability method to obtain set equations. numerically solved these equations characterize nature first- and second-order find DPT temperatures as well phases system. constructed diagrams (DPDs) reduced temperature amplitude oscillating field plane. observed that DPDs display richer, complex more topological various type diagrams. In particular, exhibit disordered phase, antiquadrupolar or staggered six different ferrimagnetic phases, three nonmagnetic numerous phases. also two tricritical points for only smaller values crystal-field interactions, multiple critical end double points, one zero-temperature point, inverse quadruple point depending on parameters. The system always shows reentrant behaviors higher amplitude, but it does not behavior parameter.

Blume-Emery-Griffiths Model on the Square Lattice with Repulsive Biquadratic Coupling
Using a real-space renormalization group procedure with no adjustable parameters, we investigate the Blume-Emery-Griffiths model on the square lattice. The formalism respects sublattice symmetry, allowing the study of both signs of K, the biquadratic exchange coupling. Our results for K > 0 are compared with other renormalization group calculations and with exact results, in order to assess the...
متن کاملPhase diagrams in the Blume-Emery-Griffiths Ising thin films
We study the spin-1 Ising model with bilinear and biquadratic exchange interactions and single-ion crystal field. In addition to the four usual phases: disordered DIS, ferromagnetic FER, antiquadrupolar AQU and ferrimagnetic FRI, we found three new phases in the case of a thin magnetic film, namely: the sublattice A non magnetic phase NMA, the sublattice B non magnetic phase NMB and the global ...
متن کاملFrustrated Blume-Emery-Griffiths model
A generalised integer S Ising spin glass model is analysed using the replica formalism. The bilinear couplings are assumed to have a Gaussian distribution with ferromagnetic mean < Jij >= J0. Incorporation of a quadrupolar interaction term and a chemical potential leads to a richer phase diagram with transitions of first and second order. The first order transition may be interpreted as a phase...
متن کاملMagnetic behavior of a spin-1 Blume-Emery-Griffiths model
I study the one-dimensional spin-1 Blume-Emery-Griffiths model with bilinear and biquadratic exchange interactions and single-ion crystal field under an applied magnetic field. This model can be exactly mapped into a tight-binding Hubbard model extended to include intersite interactions provided one renormalizes the chemical and the on-site potentials, which become temperature dependent. After ...
