Spin wave, the precession of magnetic order in magnetic materials, is a collective excitation that carries spin angular momentum. Similar to the acoustic or optical waves, the spin wave also possesses the polarization degree of freedom. Although such polarization degrees of freedom are frozen in ferromagnets, they are fully unlocked in antiferromagnets or ferrimagnets. Here we introduce the concept of magnetic gating and demonstrate a spin wave analog of the Datta-Das spin transistor in antiferromagnet. Utilizing the interplay between polarized spin wave and the antiferromagnetic domain walls, we propose a universal logic gate of pure magnetic nature, which realizes all Boolean operations in one single magnetic structure.

基于极化自旋波的磁逻辑门

自旋波是磁性材料中磁序的进动，是一种携带自旋角动量的集体激励。类似于声波或光波，自旋波还具有极化自由度。尽管这种极化自由度被冻结在铁磁体中，但它们在反铁磁体或亚铁磁体中被完全解锁。在这里，我们介绍了磁性门控的概念，并演示了反铁磁体中Datta-Das自旋晶体管的自旋波模拟。利用极化自旋波与反铁磁畴壁之间的相互作用，我们提出了一种具有纯磁性的通用逻辑门，该逻辑门可在一个磁性结构中实现所有布尔运算。
