Although a magnon parametron is known to oscillate stably near threshold, strongly excited magnetization fluctuation dynamics in the magnon parametron is unexplored. Therefore, we measured the power dependence of magnetization dynamics in a magnon parametron. Experimental results at low excitation power are consistent with single-mode numerical calculations. Experimental results at high excitation power differ from numerical calculations and suggest the existence of multiple modes.
