Magnonic logic gates represent a crucial step toward realizing fully magnonic data processing systems without reliance on conventional electronic or photonic elements. Recently, a universal and reconfigurable inverse-design device has been developed, featuring a 7 by 7 array of independent current loops that create local inhomogeneous magnetic fields to scatter spin waves in an yttrium-iron-garnet film. Although initially used for linear radio frequency components, we now demonstrate key nonlinear logic gates, NOT, OR, NOR, AND, NAND, and a half-adder, sufficient for building a full processor. In this system, binary data ("0" and "1") are encoded in the spin-wave amplitude. The contrast ratio, representing the difference between logic states, achieved values of 34, 53.9, 11.8, 19.7, 17, and 9.8 decibels for these gates, respectively.
磁子逻辑门是迈向实现完全不依赖传统电子或光子元件的全磁子数据处理系统的关键一步。最近，一种通用且可重构的逆向设计器件被开发出来，它具有一个7×7的独立电流环阵列，这些电流环会产生局部非均匀磁场，从而在钇铁石榴石薄膜中散射自旋波。尽管该器件最初用于线性射频组件，但我们现在展示了关键的非线性逻辑门，即非门、或门、或非门、与门、与非门以及一个半加器，这些对于构建一个完整的处理器来说已经足够。在这个系统中，二进制数据（“0”和“1”）被编码在自旋波幅度中。对于这些逻辑门，代表逻辑状态之间差异的对比度分别达到了34、53.9、11.8、19.7、17和9.8分贝。
