Tunable sigmoid behavior of a magnon-based parametron using a YFeO $_{12}$ /Pt bilayer disk

Emdi, G.*; Hioki, Tomosato*; Makiuchi, Takahiko*; Saito, Eiji

Sigmoidal curve behavior of 0 and n state probability in a magnon parametron, using yttrium iron garnet (YFeO $_{12}$ ) thin disk, is systematically investigated. We demonstrate that the probability distribution can be tuned by bias and pump microwave power. Our numerical calculation that considers increasing damping due to four-magnon scattering processes reproduces the results well.
