We calculate the magnetization as a function of field for an Anderson impurity model for which the lowest configurations are f¹ and f², using the leading order 1/N expansion (where N is the orbital degeneracy). For most values of the valence, except those near two, we find a two-stage crossover in M(H). This is due to an unbinding of the many-body singlet, first to a partially screened magnetic state and then to the full f² moment. At small fields there is a positive deviation from linearity in M(H) near the integer valent limits which is characteristic of degenerate f⁰-f¹ models. This upturn disappears for intermediate values of the valence.
