Abstract

It has long been believed that equilibrium random-field Ising model (RFIM) critical scattering studies are not feasible in dilute antiferromagnets close to and belowT_c(H) because of severe nonequilibrium effects. The high magnetic concentration Ising antiferromagnet Fe_0.93Zn_0.07F₂however, does provide equilibrium behavior. We have employed scaling techniques to extract the universal equilibrium scattering line shape, critical exponents ν=0.87±0.07 and η=0.20±0.05, and amplitude ratios of this RFIM system.
