| Research Abstract |
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.
