✦ Synopsis

In this work the tunneling current through a weakly coupled DQDs in an external B DC is analyzed. We propose a model which includes hyperfine interaction. The time evolution for electronic charge occupations and for the nuclei polarizations in each dot is obtained by means of rate equations which are self-consistently solved. We analyze the current in the SB region as a function of B DC and observe hysteretic behavior for magnetic fields corresponding to the crossings between triplet and singlet states. Bistability is also produced for the induced nuclei spin polarizations within each quantum dot.

Theoretical CIDNP spectra for products formed via radical pair reactions were obtained by using the transverse Cverhauser mechanism proposed by Gloss and the further constraint that the satuzated sfates have their nuclear spin configurations properiy polarized according to the sign of the electron s
