Summary
Leakage current of double quantum dot systems in the spin blockade regime has been attributed to hyperfine interactions. In this work electron transport through double quantum dots is analyzed in the spin blockade regime, in the presence of hyperfine interaction by means of rate equations. In agreement with experiment, current hysteresis as a function of magnetic field is found. This behavior comes from the interplay between dynamic nuclear spin polarization and the electronic energy states renormalization due to the Overhauser shifts induced by the nuclei.
