(Received 23 November 1998)

The conductance through two quantum dots in series is studied using general qualitative arguments and quantitative slave-boson mean-field theory. It is demonstrated that measurements of the conductance can explore the phase diagram of the two-impurity Anderson model. Competition between the Kondo effect and the interdot magnetic exchange leads to a two-plateau structure in the conductance as a function to the gate voltage and a two or three peak structure in the conductance versus interdot tunneling.

  14. However, for J > 8[radical Delta epsilon [sup 2]+t[sup 2]]/3 there will be a direct jump from N = 0 to N = 2. Since in practice J stems from superexchange between the dots, J ~ t2/U, the latter case may not be experimentally relevant, as it requires t ~ U.
