Abstract

A numerical model for a spin wave delay-line active ring resonator is presented. Spin wave dynamics along a one-dimensional strip of magnetic material are modeled using the nonlinear Schrödinger equation. The equation is solved numerically in Fourier space using the fourth-order Runge–Kutta method and yields qualitative agreement with experimental measurements of spin wave dynamics in two different regimes. The model provides a useful tool for performing experiments based on neuromorphic computing and logic gates in traveling spin wave devices.

磁性水库计算机的数值模拟

本文介绍了自旋波延迟线有源环形谐振器的数值模型。利用非线性薛定谔方程对沿一维磁性材料带的自旋波动力学进行建模。利用四阶 Runge-Kutta 方法在傅里叶空间对该方程进行了数值求解，结果与两种不同状态下的自旋波动力学实验测量结果基本一致。该模型为在行进自旋波设备中进行基于神经形态计算和逻辑门的实验提供了有用的工具。
