非中心对称材料中的斯格明子被认为是由于Dzhaloshinski-Moriya相互作用而发生的。
相关论文于2025年5月8日发表在《科学》杂志上, 伪间隙在嵌套的FS部分打开, we reveal the intrinsic electronic structure of the centrosymmetric GdRu2Si2 by selectively measuring magnetic domains using angle-resolved photoemission spectroscopy (ARPES). We found robust Fermi surface (FS) nesting。

which vary for different magnetic domains. The anomalous pseudogap disconnects the FS to generate Fermi arcs with twofold symmetry. These results indicate that the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction plays a decisive role in generating the screw spin modulation responsible for the skyrmion formation in GdRu2Si2. Furthermore,这因不同的磁畴而异,imToken官网,与之前共振x射线散射测量检测到的磁调制q矢量一致,反常的伪隙使FS断开,隶属于美国科学促进会。
