Second-order phase transitions and tricritical points in the random-field Ising models

A method that applies to a wide class of the random-field Ising models is used to investigate the influence of random-field on the critical phenomena. The 3D random-field Ising models with nearest-neighbour interactions exhibit tricritical behavior. The obtained results express rather large deviations from the mean-field theory. For particular cases, the formulation gives some well-known exact results.
