Unconventional computing schemes based on bistable systems ("Ising spins") may supersede conventional computing paradigms. The "magnon parametron"is an Ising spin that forms as a result of parametric excitation of a ferromagnetic particle by microwaves beyond a certain threshold. This Ising spin becomes unstable at a second threshold power at which a high-frequency telegraph noise emerges. We explain the experimentally observed stochastic switching ("p-bit"characteristics) at room temperature by the Suhl instability of the uniform magnetization precession.
