Pauli spin blockade in the cotunneling transport through an effective two-electron double quantum dot (™10 electrons in each dot) has been presented. In the cotunneling regime where the two-electron (1,1) and (0,2) states (ordered pairs denote the effective electron numbers in each dot) are far below the Fermi energy of the leads, we can concentrate on the two-electron tunnelling transitions and detect singlet-triplet splitting arising from the exchange interaction between the two electron spins with improved resolution. We discuss the cotunneling transport by considering the coherent and incoherent coupling between the dots in connection with the singlet-triplet splitting.
