We report on theoretical studies of a recently discovered strong radiation-induced magnetoresistance spike obtained in ultraclean two-dimensional electron systems at low temperatures. The most striking feature of this spike is that it shows up on the second harmonic of the cyclotron resonance. We apply the radiation-driven electron orbits model in the ultraclean scenario to offer a theoretical approach of this striking effect. We explain the effect of an in-plane magnetic field on the spike which consists in a vanishing effect when this field increases.
