The orbital magnetization and its effects on the two-dimensional kagomé lattice with spin anisotropies included in the general Hund's coupling region have been theoretically studied. The results show that the strength of the Hund's coupling, as well as the spin chirality, contributes to the orbital magnetization $\mathcal{M}$. Upon varying both these parameters, it is found that the two parts of $\mathcal{M}$, i.e., the conventional part $\mathbf{M}_{c}$ and the Berry-phase correction part $\mathbf{M}_Ω$, oppose each other. The anomalous Nernst conductivity is also calculated and a peak-valley structure as a function of the electron Fermi energy is obtained.
Robust magnetotransport in disordered ferromagnetic kagome layers with quantum anomalous Hall effect
对无序铁磁可果美层的磁输运性质进行了数值研究。我们发现在可果美层状材料（如Fe $_3$ Sn $_2$，Co $_3$ Sn $_2$ S $_2$，和Mn $_3$ Sn）中可以实现大的畴壁磁电阻或负磁电阻，表现出量子反常霍尔效应.戈薇层表现出强烈的磁各向异性和大的磁阻取决于它们的磁织构。这些畴壁磁阻预计将是强大的，对无序和观察无关的畴壁厚度，在铁磁金属中的常规畴壁磁阻。

我们报告了由互连Ni $_{80}$ Fe $_{20}$纳米棒大阵列制成的可果美人造自旋冰（ASI）的宽带自旋波光谱。在饱和和无序状态下拍摄的光谱表现出一系列具有特征磁场依赖性的共振。利用微磁学模拟，我们确定的共振，反映了自旋固体状态和狄拉克字符串的反自旋对。后者的谐振允许通过微波辅助切换在ASI中产生高电荷顶点。我们的研究结果打开了进一步的前景，对ASI的基础研究及其在可重编程磁振子的使用。
