Abstract: We report on the basic properties of recently observed magnetic fieldresonance, induced time dependent oscillation, and hysteresis effects in thecurrent flowing through two weakly coupled vertical quantum dots at highsource-drain bias up to a few tens of mV. These effects bare some similarityto those reported in the N=2 spin-blockade regime, usually for weak in-planemagnetic field, of quantum dot molecules and attributed to hyperfine coupling,except here the measurements are conducted outside of the spin-blockade regimeand the out-of-plane magnetic field is up to ~6 T.
