Self-organization and Novel Magneto-transport Phenomena by Partial Kondo Screening in Kondo Systems

从理论上研究了巡回电子与局域自旋相互作用的Kondo晶格系统中几何受挫的影响。特别是，我们通过对部分近藤屏蔽的关注来阐明其特殊的磁性和输运性质，这是磁性和非磁性位置空间共存的部分无序的一个特殊例子。此外，我们还研究了受阻巡游电子系统中有趣的物理问题，如导致反常霍尔效应的自旋标量手性的稳定机制以及局域自旋关联引起的非平凡输运性质。

Effects of geometrical frustration are theoretically investigated in the Kondo lattice systems in which itinerant electrons interact with localized spins. In particular, we clarified the peculiar magnetic and transport properties with focusing on the partial Kondo screening, which is a peculiar example of the partial disorder with a spatial coexistence of magnetic and nonmagnetic sites. In addition, we also studied the intriguing physics in frustrated itinerant electron systems, such as the stabilization mechanism of the spin scalar chirality leading to the anomalous Hall effect and nontrivial transport properties due to local spin correlations.
