论文摘要
我们报告了实验，证明了在抗铁磁绝缘子赤铁矿的薄膜中对镁自旋转运和假蛋白动力学的相干控制，利用两条PT条进行了全电镁注射和检测。检测器处的测得的镁自旋信号揭示了其极性与外部施加磁场的函数的振荡。我们用易于平面各向异性和dzyaloshinskii-moriya相互作用引起的镁化蛋白的扩散木元传输和相干性进攻来定量解释我们的实验。该实验性观察可以看作是电子汉尔效应和达塔 - das晶体管的宏伟类似物，从而使抗磁磁性镁的高潜力旨在实现富电子设备启发的现象。
We report on experiments demonstrating coherent control of magnon spin transport and pseudospin dynamics in a thin film of the antiferromagnetic insulator hematite utilizing two Pt strips for all-electrical magnon injection and detection. The measured magnon spin signal at the detector reveals an oscillation of its polarity as a function of the externally applied magnetic field. We quantitatively explain our experiments in terms of diffusive magnon transport and a coherent precession of the magnon pseudospin caused by the easy-plane anisotropy and the Dzyaloshinskii-Moriya interaction. This experimental observation can be viewed as the magnonic analogue of the electronic Hanle effect and the Datta-Das transistor, unlocking the high potential of antiferromagnetic magnonics towards the realization of rich electronics-inspired phenomena.
