Ising Replicated System of ± J Model
Abstract
The nreplicated system described by the Ising spin with the random exchange interactions ± J is separated into two subsystems, namely, the spindependent part and the spinindependent part. It is pointed out that although for n<1 the entropy and specific heat contributed from the spindependent part are negative, those of the whole system are always positive. It is shown that from the spindependent part the Mattis type phase essentially described by an asymptotic Potts model appears at finite n and vanished for n to 0 (the quenched limit).
