Critical Point Phenomena and Phase Transitions in the Ising Model
A Monte Carlo simulation of the Ising Model, a simplified model for studying the behavior of magnetic materials at various temperatures, was constructed. This model illustrated the transition between magnetic and non-magnetic phases as temperature is increased, and showed critical-point behavior at the transition. A general system for studying the behavior of many different configurations of pa...
متن کاملMonte Carlo studies of critical phenomena in mixed spin-3/2 and spin-5/2 Ising model on square lattice
We used a Monte Carlo simulation to analize the magnetic behavior of Ising model of mixed spins S i = ±3/2,±1/2 and σ j = ±5/2,±3/2,±1/2, on a square lattice. Were studied the possible critical phenomena that may emerge in the region around the multiphase point (D/|J1| = −3, J2/|J1| = 1) and the dependence of the phase diagrams with the intensities of the anisotropy field of single ion (D/|J1|)...
متن کاملISING CRITICAL BEHAVIOR IN SPIN GLASSES : Fe0.25Zn0.75F2
We present a scaling analysis of the nonlinear susceptibility data above the freezing temperature in the spin glass system Fe0.25Zn0.75F2. The critical exponents obtained are in excellent agreement with those found in metallic systems and are also compatible with theoretical predictions for short range Ising spin glasses. The randomly diluted highly anisotropic antiferromagnet Fe,Znl-,Fz with x...
متن کاملMagnetic 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 کاملOn the Mean Euler Characteristic and Mean Betti's Numbers of the Ising Model with Arbitrary Spin *
The behaviour of the mean Euler–Poincaré characteristic and mean Betti’s numbers in the Ising model with arbitrary spin on Z2 as functions of the temperature is investigated through intensive Monte Carlo simulations. We also consider these quantities for each color a in the state space SQ = {−Q,−Q + 2, . . . , Q} of the model. We find that these topological invariants show a sharp transition at...
