AI 中文摘要
反铁磁体因其交替的自旋取向可抵消净磁化强度，在下一代具有更高频率和可扩展性的自旋电子器件中具有诱人的应用潜力。然而，由于其不存在非零磁化强度，反铁磁体的磁构型检测困难，阻碍了其应用。本文中，我们在非共线反铁磁体$\text{MnTe}_{2}$中报道了一种新的横向输运效应。该效应在磁场和奈尔序上均为反对称，但在其两个指标上对称，可通过磁场和几何量共同诱导的贡献来解释，这一点得到了我们理论计算的证实。我们关于新的奈尔序依赖横向输运效应的发现，为推进反铁磁自旋电子学提供了机遇。
英文摘要
Antiferromagnets hold appealing potential in next-generation spintronic devices with higher frequency and scalability, thanks to their alternating spin orientations that cancel out net magnetization. However, the lack of a nonzero magnetization makes the detection of the magnetic configuration of antiferromagnet difficult, hampering the applications of antiferromagnets. Here, we report a new transverse transport effect in noncoplanar antiferromagnet $\text{MnTe}_{2}$. This effect is antisymmetric in both magnetic field and Néel order, but symmetric in its two indices. It can be understood in terms of the contribution induced by both magnetic field and geometric quantities, as confirmed by our theoretical calculations. Our discovery of a new Néel-order-dependent transverse transport effect provides opportunities to the advancing antiferromagnetic spintronics.
