Tomography of parametric transition in magnets

Shimizu, Hiroki*; Hioki, Tomosato*; Takeda, Shuntaro*; Saito, Eiji

Temporal evolution of Wigner functions representing fluctuation distribution of magnetization in YFeO $_{12}$ (YIG) at the moment of parametric oscillation onset has been investigated. Our newly developed time-resolved spectroscopy unmasks that highly distorted and stretched correlation of magnetization fluctuation leads the parametric oscillation, being consistent with numerical simulation incorporating nonlinear four-magnon scattering. The method offers a powerful tool for probing nonlinear dynamics in a variety of magnets.
