✦ Synopsis

A theory is presented of spin-glasses with nam/3l<< 1, where nm is the magnetic impurity concentration and I the mean free path (this corresponds to a large concentration of nonmagnetic defects). The specific heat, susceptibility, and resistivity are derived. Five temperature ranges can be distinguished in which all of these exhibit different behavior. The nature of the transition is discussed. The physical conditions for the applicability of the model are considered.
