    • All of the simulation results shown in this paper are specific to the simulation conditions described in Fig. and the text. The ten types of pulse sequences shown in Fig. were also demonstrated for the " " and " p-PLUS-c " switchings for another conditions while holding p Spol =-1. With the other conditions for p Spol =+1, there were neither gyrotropic motion and nor any switching.
