摘要：

The extinction-free neutron scattering for a 3.4 mu m epitaxial film of the dilute antiferromagnet Fe0.5Zn0.5F2 has been studied near the (100) magnetic Bragg point. For the H = 0 Bragg scattering we observe the random-exchange Ising model behavior I similar to \t\(2 beta) with beta = 0.35. For 0 < H < = 4.5 T the random-field Ising peak intensity vs. T has the opposite curvature from the H = 0 case near T-c(H).
