Abstract

van der Waals antiferromagnetic insulators are emerging as promising candidates for spintronics and quantum computing due to their unique magnetic properties. However, detecting antiferromagnetism at the atomic scale remains challenging due to compensated spin order. In this study, we present a novel approach to observe the antiferromagnetic proximity effect in FePS₃/Pt heterostructures. This effect arises from interfacial magnetic moments, which induce significant spin polarization in the Pt layer via strong interlayer exchange interactions. As a result, a pronounced anomalous Hall effect is observed in the Pt layer. Fe atom vacancies at the FePS₃/Pt interface play a critical role in creating localized surface magnetic moments and enhancing exchange interactions. These findings shed light on the complex interplay between two-dimensional antiferromagnetic insulators and heavy metals with strong spin-orbit coupling, providing a promising strategy to exploit interfacial effects for creating magnetization in antiferromagnetic materials.

FePS3/Pt非补偿界面上的范德华反铁磁邻近效应。

范德华反铁磁绝缘体由于其独特的磁性而成为自旋电子学和量子计算的有希望的候选者。然而，由于自旋顺序的补偿，在原子尺度上检测反铁磁性仍然具有挑战性。在这项研究中，我们提出了一种新的方法来观察FePS3/Pt异质结构中的反铁磁邻近效应。这种效应是由界面磁矩引起的，界面磁矩通过强的层间交换作用在Pt层中诱导了显著的自旋极化。结果，在铂层中观察到明显的异常霍尔效应。FePS3/Pt界面上的铁原子空位在产生局域表面磁矩和增强交换相互作用中起着关键作用。这些发现揭示了二维反铁磁绝缘体与具有强自旋轨道耦合的重金属之间复杂的相互作用，为利用界面效应在反铁磁材料中产生磁化提供了一种有前途的策略。

期刊介绍： Materials Horizons is a leading journal in materials science that focuses on publishing exceptionally high-quality and innovative research. The journal prioritizes original research that introduces new concepts or ways of thinking, rather than solely reporting technological advancements. However, groundbreaking articles featuring record-breaking material performance may also be published. To be considered for publication, the work must be of significant interest to our community-spanning readership. Starting from 2021, all articles published in Materials Horizons will be indexed in MEDLINE©. The journal publishes various types of articles, including Communications, Reviews, Opinion pieces, Focus articles, and Comments. It serves as a core journal for researchers from academia, government, and industry across all areas of materials research. Materials Horizons is a Transformative Journal and compliant with Plan S. It has an impact factor of 13.3 and is indexed in MEDLINE.
