Abstract

Description

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 being investigated and equilibrium critical behavior is being characterized at high magnetic concentrations.
