Electrically driven spin resonances in double quantum dots can lift the spin blockade and give rise to a resonant current. This current can probe the properties of coupled two-spin states for different quantum dot configurations. Using a Floquet-Markov quantum transport model we compute the resonant current for different driving amplitudes and ac field frequencies in spin-orbit coupled quantum dots. We show that the resonant current has a very rich interference pattern which can give valuable insight into the singlet-triplet state mixing.
