摘要：

The effects of a random field on the transition temperature in a quenched site-diluted Ising ferromagnet with coordination number z = 3 are investigated by the use of the effective-field theory with correlations. We find that the critical concentration of magnetic atoms at which the transition temperature reduces to zero depends on a random field. The influence of the dilution on the re-entrant phenomenon is also studied.
