Abstract
We investigate the Ising model on the square lattice with correlated random fields which take the values ±h0 and 0. The random fields are assumed to vary from row to row but not from column to column. In the limit [MATH] ? 0, the system shows the phase transition, where [MATH] is the uniform external field with [MATH] ? h0.
