Tomography of Parametric Transition in Magnets
Temporal evolution of Wigner functions representing fluctuation distribution of magnetization in Y_{3}Fe_{5}O_{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.
