Abstract. This is a sequel to the author's earlier studies of large deviations of nonstationary stochastic processes, or `disordered spins'. As an application of the general theorems, this paper studies a Curie-Weiss-type mean-field model of a quenched mixed magnetic crystal. This model has quenched site disorder and frustration but non-random coupling constants. It turns out to exhibit a continuous phase transition with critical exponents equal to those of the classical Curie-Weiss theory.
