We investigate the slow transient buildup of leakage current influenced by dynamic spin polarization (DNP) in the spin blockade region of a double quantum dot (DQD). We focused on slightly off-resonant conditions, where the current is extremely small with nominally unpolarized nuclear spins. Leaving the system in such a situation causes the current to increase stepwise twice. Such transient current steps can be understood by considering that at the first step inhomogeneous nuclear spin polarization significantly increases while at the second step stable polarization is attained. We believe that the DNP produces a feedback effect.
