We electrically detect the resonant absorption of microwaves by a two‐dimensional electron gas modulated by a periodic magnetic field with zero average. The quantum interferences of two resonant spin flip transitions, one propelled by microwaves the other by snake orbits block spin flips hence the propagation of snake orbits. The resistance peak is found to be proportional to the probability of the hybrid quantum state produced by these interferences.
