Monte Carlo studies of spin glasses universally exhibit a ‘‘zero-field hole’’ in the distribution of local fields, P(h). There is some dispute in the literature as to whether the dilute antiferromagnetic Ising model on the triangular lattice has a spin-glass phase; in this paper we present Monte Carlo results for P(h) which further support the hypothesis that indeed this system does exhibit a spin-glass phase.
