论文摘要
范德华材料是研究二维系统的新平台，包括磁顺序。由于旋转的数量相对较小，因此测量磁化强度是具有挑战性的。在这里，我们报告了由磁性范德华材料的去角质薄片引起的旋转霍尔磁性（SMR），直到室温。对于抗fiferromagnet FEPS3，对于5 k时的7 t施加的磁场，SMR为0.1％，这意味着相对于Colinear抗抗铁磁序的磁矩实质性倾斜。即使对于沿NéelVector的磁场，倾斜也很大，这说明了SMR检测范德华磁体中磁表面纹理的独特功能。
Van der Waals materials are a new platform to study two-dimensional systems, including magnetic order. Since the number of spins is relatively small, measuring the magnetization is challenging. Here we report spin Hall magnetoresistance (SMR) up to room temperature caused by the magnetic surface texture of exfoliated flakes of magnetic van der Waals materials. For the antiferromagnet FePS3 the SMR amounts to 0.1 % for an applied magnetic field of 7 T at 5 K which implies a substantial canting of the magnetic moments relative to the colinear antiferromagnetic order. The canting is substantial even for a magnetic field along the Néel vector, which illustrates the unique power of the SMR to detect magnetic surface textures in van der Waals magnets.
