Outline of Final Research Achievements

In this project, we have studied correlation effects in f-electron superlattices. We have investigated (1) Kondo effect and electrical resistivity, (2) antiferromagnetism and superconductivity, and (3) ferromagnetism. (1) Impacts of superlattice structures on Kondo effect have been examined. Resistivity of the heavy fermions formed in the superlattice was also studied. (2) We have discussed the competition between antiferromagnetic RKKY interaction and Kondo effect. Superconductivity mediated by itinerant spin fluctuations was also discussed. (3) We have studied a possible ferromagnetic quantum critical point and magnetoresistance in Kondo superlattices.
