论文摘要
Kitaev材料的性质由于其外在特性而引起了越来越多的关注。在现实的二维材料中，基塔夫相互作用通常伴随着dzyloshinskii-moriya的相互作用，这构成了分别区分其幅度的挑战。在这项工作中，我们证明可以通过访问宏伟的运输特性来完成。通过同时研究表现出dzyaloshinskii-moriya和Kitaev相互作用的蜂窝铁磁铁，我们揭示了非平凡的镁性拓扑特性，并伴随着由Thermal Hall和Magnon Nernst Effects给出的复杂的岩石传输特性。我们还研究了磁场的效果，表明它不仅打破了系统的对称性，而且还为宏伟的拓扑传输特性带来了巨大的修饰，这是各向异性交换相互作用相对强度的标志。根据我们的发现，我们建议采取策略来估算实际材料中Kitaev相互作用的重要性。
The properties of Kitaev materials are attracting ever increasing attention owing to their exotic properties. In realistic two-dimensional materials, Kitaev interaction is often accompanied by the Dzyloshinskii-Moriya interaction, which poses a challenge of distinguishing their magnitude separately. In this work, we demonstrate that it can be done by accessing magnonic transport properties. By studying honeycomb ferromagnets exhibiting Dzyaloshinskii-Moriya and Kitaev interactions simultaneously, we reveal non-trivial magnonic topological properties accompanied by intricate magnonic transport characteristics as given by thermal Hall and magnon Nernst effects. We also investigate the effect of a magnetic field, showing that it does not only break the symmetry of the system but also brings drastic modifications to magnonic topological transport properties, which serve as hallmarks of the relative strength of anisotropic exchange interactions. Based on our findings, we suggest strategies to estimate the importance of Kitaev interactions in real materials.
