Mean field estimates of T(g) for short-range spin glasses.

A heuristic percolation model incorporating the effects of frustration in a mean field sense describes spin glass transitions. The model shows that below T(g) in equilibrium long-range order is present just as in ordinary magnetic transitions. For the Ising simple cubic +J/-J spin glass KT(g)(I) = 1.25J, in excellent agreement with the results of recent numerical simulations.
