Abstract

This article examines recent advances in the field of antiferromagnetic spintronics from the perspective of potential device realization and applications. We discuss advances in the electrical control of antiferromagnetic order by current-induced spin–orbit torques, particularly in antiferromagnetic thin films interfaced with heavy metals. We also review possible scenarios for using voltage-controlled magnetic anisotropy as a more efficient mechanism to control antiferromagnetic order in thin films with perpendicular magnetic anisotropy. Next, we discuss the problem of electrical detection (i.e., readout) of antiferromagnetic order and highlight recent experimental advances in realizing anomalous Hall and tunneling magnetoresistance effects in thin films and tunnel junctions, respectively, which are based on noncollinear antiferromagnets. Understanding the domain structure and dynamics of antiferromagnetic materials is essential for engineering their properties for applications. For this reason, we then provide an overview of imaging techniques as well as micromagnetic simulation approaches for antiferromagnets. Finally, we present a perspective on potential applications of antiferromagnets for magnetic memory devices, terahertz sources, and detectors.
反铁磁自旋电子器件的前景
本文从潜在设备实现和应用的角度探讨了反铁磁自旋电子学领域的最新进展。我们讨论了通过电流诱导的自旋轨道力矩对反铁磁秩序进行电控制的进展,特别是在与重金属连接的反铁磁薄膜中。我们还回顾了在具有垂直磁各向异性的薄膜中使用电压控制磁各向异性作为控制反铁磁秩序的更有效机制的可能方案。接下来,我们将讨论反铁磁阶的电学检测(即读出)问题,并重点介绍在薄膜和隧道结中分别实现反常霍尔效应和隧道磁阻效应的最新实验进展,这些都是基于非共轭反铁磁体。了解反铁磁性材料的磁畴结构和动力学对于设计其应用特性至关重要。为此,我们将概述反铁磁体的成像技术和微磁模拟方法。最后,我们将介绍反铁磁体在磁存储器件、太赫兹源和探测器方面的潜在应用。
