Abstract
We present a solvable kinetic lattice model which includes microscopic disorder, namely, random exchange energies (between pairs of spins) f luctuating randomly with time. This, which may ideally model fast ioni c diffusion in magnetic systems, impedes reaching equilibrium, in gene ral. The resulting nonequilibrium steady states exhibit additional ran domness which induces complex behavior, including reentrance phenomena reminiscent of spin-glass behavior. [S0163-1829(98)02738-6].
