The Critical Behavior of a Transverse Ferromagnet Spin-l/2 Ising Superlattice
نویسنده
چکیده
Using the effective field theory that accounts for the self-spin correlation function, the critical behavior of a magnetic superlattice consisting of two different ferromagnets is examined in a transverse spin-l/2 Ising model. The dependence of the critical temperature on the thickness of the constituents in a unit cell is investigated for different cases. A critical value of the interface exchange coupling above which the interface magnetism appears is found. The effect of the transverse field on the system is also investigated.

Magnetic 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.

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 کاملEffect of disorder on quantum phase transitions in anisotropic XY spin chains in a transverse field
We present some exact results for the effect of disorder on the critical properties of an anisotropic XY spin chain in a transverse field. The continuum limit of the corresponding fermion model is taken and in various cases results in a Dirac equation with a random mass. Exact analytic techniques can then be used to evaluate the density of states and the localization length. In the presence of ...
متن کاملReentrant transitions of Ising-Heisenberg ferromagnet on a triangular lattice with diamond-like decorations
The mixed spin-1/2 and spin-1 Ising-Heisenberg ferromagnet on the decorated triangular lattice consisting of inter-connected diamonds is investigated within the framework of an exact decoration-iteration mapping transformation. It is shown that the diamond-like decoration by a couple of the Heisenberg spins gives rise to a diverse critical behaviour including reentrant phase transitions with tw...
متن کاملIsing quantum Hall ferromagnet in magnetically doped quantum wells.
We report on the observation of the Ising quantum Hall ferromagnet with Curie temperature T(C) as high as 2 K in a modulation-doped (Cd,Mn)Te heterostructure. In this system field-induced crossing of Landau levels occurs due to the giant spin-splitting effect. Magnetoresistance data, collected over a wide range of temperatures, magnetic fields, tilt angles, and electron densities, are discussed...
