Abstract

We report the electrical induction and detection of dynamic nuclear polarization in the spin-blockade regime of double GaAs vertical quantum dots. The largest Overhauser field observed was about 4 Tesla, corresponding to a nuclear polarization of about 40% in the present device. A phenomenological model is presented to provide a qualitative understanding of our results.
