Ferrimagnetism in Diluted Mixed Spin-1/2 and Spin-3/2 Ising Systems
Using an effective field theory with correlations we study a diluted mixed spin-112 and spin-312 Ising ferrimagnetic system with a crystal field interaction D(D < 0) on a honeycomb lattice. We find that the system may exhibit two compensation points in the total magnetization curve, although the corresponding system in the absence of dilution or with D = 0 never exhibits any compensation point ...
متن کاملAperiodic spin chain in the mean-field approximation
Surface and bulk critical properties of an aperiodic spin chain are investigated in the framework of the φ phenomenological Ginzburg-Landau theory. According to Luck’s criterion, the mean field correlation length exponent ν = 1/2 leads to a marginal behaviour when the wandering exponent of the sequence is ω = −1. This is the case of the Fibonacci sequence that we consider here. We calculate the...
متن کاملThree-dimensional Ising spin-glasses and mean-field theory
2014 The results of a simulation of a three-dimensional nearest neighbour Ising spin-glass are presented and compared with mean-field theory predictions. It is found that the order parameter P(q) has a similar behaviour in the short-range coupling and in the infinite-range coupling model. Tome 45 No 20 15 OCTOBRE 1984 LE JOURNAL DE PHYSIQUE LETTRES J.

متن کاملMean Field Dynamical Exponents in Finite - Dimensional Ising Spin Glass
We report the value of the dynamical critical exponent z for the six dimensional Ising spin glass, measured in three different ways: from the behavior of the energy and the susceptibility with the Monte Carlo time and by studying the overlap-overlap correlation function as a function of the space and time. All three results are in a very good agreement with the Mean Field prediction z = 4. Fina...
متن کاملIsing spin glass with arbitrary spin beyond the mean field theory.
We consider the Ising spin glass for the arbitrary spin S with the short-ranged interaction using the Bethe-Peierls approximation previously formulated by Serva and Paladin [Phys. Rev. E. 54, 4637 (1996)] for the same system but limited to S=1/2. Results obtained by us for arbitrary S are not a simple generalization of those for S=1/2. In this paper we mainly concentrate our studies on the calc...
