论文摘要
Twistronics的兴起彻底改变了凝结物理学的领域，更具体地说是二维材料的未来应用。在小扭曲角度，微观世界变得强烈相关，并且出现了意外的物理现象，例如超导性。对于磁性层，堆叠在导致非平凡旋转构型的磁性交换耦合中起着至关重要的作用。在这项工作中，我们简要概述了最新的理论和实验著作，该作品报告了扭转角对二维磁体的影响。此外，我们讨论了扭曲角度和局部抗铁磁层间交换耦合对三亚甲酸铬铬磁体结构域形成的影响。最后，我们对堆叠效果和扭曲角度对双层cri $ _3 $的自旋波分散体的影响显示了一些初步结果。
The rise of twistronics has revolutionized the field of condensed matter physics, and more specifically the future applications of two-dimensional materials. At small twist angles, the microscopic world becomes strongly correlated, and unexpected physical phenomena such as superconductivity emerge. For magnetic layers, stacking plays a crucial role in the magnetic exchange coupling between the layers leading to non-trivial spin configurations and flat spin-wave dispersion when twisted. In this work, we give a short overview of the most recent theoretical and experimental works reporting the effect of twist angles on two-dimensional magnets. Besides, we discuss the effect of the twist angle and the local antiferromagnetic interlayer exchange coupling on the formation of antiferromagnetic domains in chromium trihalides. Finally, we show some preliminary results on the effect of the stacking and the twist angle on the spin-wave dispersion of bilayer CrI$_3$
