Magnetic Properties in a Spin-1 Random Transverse Ising Model on Square Lattice
In this paper we investigate the effect of a random transverse field, distributed according to a trimodal distribution, on the phase diagram and magnetic properties of a two-dimensional lattice (square with z=4), ferromagnetic Ising system consisting of magnetic atoms with spin-1. This study is done using the effectivefield theory (EFT) with correlations method. The equations are derived using...
متن کاملMagnetic Properties and Phase Transitions in a Spin-1 Random Transverse Ising Model on Simple Cubic Lattice
Within the effective-field theory with correlations (EFT), a transverse random field spin-1 Ising model on the simple cubic (z=6) lattice is studied. The phase diagrams, the behavior of critical points, transverse magnetization, internal energy, magnetic specific heat are obtained numerically and discussed for different values of p the concentration of the random transverse field.
متن کاملThe Fully Frustrated Hypercubic Model is Glassy and Aging at Large D
We discuss the behavior of the fully frustrated hypercubic cell in the infinite dimensional mean-field limit. In the Ising case the system undergoes a glass transition, well described by the random orthogonal model. Under the glass temperature aging effects show clearly. In the XY case there is no sign of a phase transition, and the system is always a paramagnet.
متن کاملGlassy transition in the three-dimensional random-field Ising model.
The high temperature phase of the three dimensional random field Ising model is studied using replica symmetry breaking framework. It is found that, above the ferromagnetic transition temperature Tf , there appears a glassy phase at intermediate temperatures Tf < T < Tb while the usual paramagnetic phase exists for T > Tb only. Correlation length at Tb is computed and found to be compatible wit...
متن کاملPhase Transitions in Relaxor Ferroelectrics
This paper covers the properties of relaxor ferroelectrics and considers the transition from the paraelectric state to the relaxor state comparing experimental data with the spherical random-bond randomfield model (SRBRF). It found that this model predicts and is experimental verifies a glassy state at the transition temperature for E < Ec and a ferroelectric state with quench random fields for...
