Abstract
We introduce a class of exactly solvable models exhibiting an ordering nois e-induced phase transition in which order arises as a result of a balance b etween the relaxing deterministic dynamics and the randomizing character of the fluctuations. A finite-size scaling analysis of the phase transition r eveals that it belongs to the universality class of the equilibrium Ising m odel. All these results are analyzed in the light of the nonequilibrium pro bability distribution of the system, which can be obtained analytically. Ou r results could constitute a possible scenario of inverted phase diagrams i n the so-called lower critical solution temperature transitions.
