The two-dimensional Ising model with disorder in the spin-spin interactions is studied using the zeros of the energy probability distribution (EPD) to obtain the phase diagram of the quenched three-dimensional ( L 3 ) ± J Ising model. Starting with a complete ferromagnetic (anti-ferromagnetic) system, we introduce at random a number of p × L 3 anti-ferromagnetic (ferromagnetic) bonds in the system. The phase diagram, temperature against the bond concentration (p), is obtained. The goal of this preliminary study is to show how it is possible to determine the phase diagram of such a complex model with no need to introduce an order parameter. [ABSTRACT FROM AUTHOR] |
