| Popis: | A formulation of the dilute bond Ising model is derived in terms of an equivalent Hamiltonian. A temperature concentration phase diagram is proposed. It is shown that, although no spin-glass is expected, the confluence at T=0 of the respective conditions for ferromagnetic and spin-glass transitions to occur induces the low temperature crossover to percolation behaviour. |
