BELANGER, D. P.. Experimental characterization of the Ising model in disordered antiferromagnets. Braz. J. Phys. [online]. 2000, vol.30, n.4, pp. 682-692. ISSN 0103-9733. http://dx.doi.org/10.1590/S0103-97332000000400009.
The current status of experiments on the d = 2 and d = 3 random-exchange and random-field Ising models, as realized in dilute anisotropic antiferromagnets, is discussed. Two areas of current investigation are emphasized. For d = 3, the large random field limit is investigated and equilibrium critical behavior is characterized at high magnetic concentrations.
