Resumen:
Two different site order parameters are considered to characterize the partial spin-glass behavior
of J square Ising lattices. On the one hand, q proposed by Edwards and Anderson two decades
ago; on the other p, a more drastic parameter introduced recently. Site order parameters depend
very strongly on the way ergodic separation is performed. Here, we deal with three dierent ways
of doing so, thus allowing to nd the most representative parameter with the appropriate ergodic
separation, to have a more sensitive method to characterize the spin-glass phase. Implications of
clustering in the con guration space on order parameters are also discussed. c 2000 Elsevier
