摘要：

The high-magnetic concentration Ising antiferromagnet Fe0.93Zn0.07F2 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-held Ising model critical behavior. (C) 1998 Elsevier Science B.V. All rights reserved.
