Magnetization dynamics induced by parametric excitation in a magnetic dot has been investigated by using ac spin pumping and inverse spin-Hall effects. An Ising-like pair of states with different precession phases was found to be stabilized in a controllable way under the excitation. The result shows that the dot can be used as a parametron-bit carrier. Upon increasing the excitation power, stochastic transition between the states was observed, and the occurrence probability of each state can be tuned by means of additional microwaves, opening an application to probabilistic bit operation.
