The authors present a theory of the freezing temperature Tg of metallic spin glasses. Length scales associated with intrinsic sd scattering and finite temperature play essential roles. They describe an approach in which Tg is calculated directly in terms of the strength and range of the effective spin-spin pair interactions. The theory leads to a clear physical picture of the dependence of Tg on the concentration and type of impurities in the spin glass, and provides a comprehensive account of a wide range of experimental data
