Spin-glass phase transition and behavior of nonlinear susceptibility in the Sherrington-Kirkpatrick model with random fields

C. V. Morais, F. M. Zimmer, M. J. Lazo +2

The behavior of the nonlinear susceptibility ${\chi }_3$ and its relation to the spin-glass transition temperature $T_f$, in the presence of random fields, are investigated. To accomplis…
