Magnetization dynamics induced by parametric pumping has been investigated by numerically calculating a master equation. The results show that a weak microwave with the same frequency as the ferromagnetic resonance, a bias microwave, can be used to control which phase state appears under a parametric excitation. The amplitude dependence of the appearance probability exhibits sigmoid-like behavior. We have also found that a strong microwave causes an amplitude squeezed state with a sub-Poissonian distribution, which has a potential to serve as a quantum information resource.
