In this work we use the zeros of the energy probability distribution to obtain the critical diagram of the three dimensional ( L 3 ) ± J Ising model. Starting with a complete ferromagnetic system we introduce a number of p × L 3 antiferromagnetic bonds in the system. The phase diagram, temperature against antiferromagnetic bond concentration ( p ), is estimated for several values of p . The goal of this preliminary study is to show how it is possible to determine the phase diagram of such a complex model without the need to define any order parameter.
