Abstract

The high-magnetic concentration Ising antiferromagnet Fe_0.93Zn_0.07F₂ does not exhibit the severe critical scattering hysteresis at low temperatures observed in all the lower concentration samples studied. The system, therefore, provides equilibrium neutron scattering line shapes suitable for determining random-field Ising model critical behavior.
