| 1 | A nonlinear magnonic nano-ring resonator显示文摘The field of magnonics,which aims at using spin waves as carriers in data-processing devices,has attracted increasing interest in recent years.We present and study micromagnetically a nonlinear nanoscale magnonic ring resonator device for enabling implementations of magnonic logic gates and neuromorphic magnonic circuits.In the linear regime,this device efficiently suppresses spin-wave transmission using the phenomenon of critical resonant coupling,thus exhibiting the behavior of a notch filter.By increasing the spin-wave input power,the resonance frequency is shifted,leading to transmission curves,depending on the frequency,reminiscent of the activation functions of neurons,or showing the characteristics of a power limiter.An analytical theory is developed to describe the transmission curve of magnonic ring resonators in the linear and nonlinear regimes,and is validated by a comprehensive micromagnetic study.The proposed magnonic ring resonator provides a multi-functional nonlinear building block for unconventional magnonic circuits. | Qi Wang Abbass Hamadeh Roman Verba Vitaliy Lomakin Morteza Mohseni Burkard Hillebrands Andrii V.Chumak Philipp Pirro | 2020 | npj Computational Materials2020，，1： | 0 |
