In this study, the generation of spin-wave soliton trains was achieved by self-modulation instability using only a single input pulse. This achievement enables the generation of soliton trains with a transmission density 10 times higher than that of the conventional method of generating soliton trains using a feedback ring. This findings are expected to be applied to high-intensity and high-density information processing devices using spin waves.
