Outline of Final Research Achievements |
Well-defined surfaces and interfaces of f-electron systems have been realized by using molecular beam epitaxy technique. We have grown hybrid-type superlattices comprising of the heavy-fermion superconductor CeCoIn5 and antiferromagnetic metal CeRhIn5. We have found that the superconducting properties changes dramatically by applying pressure, implying that the injection of the magnetic fluctuation through the interface plays an important role to control the nature of superconducting electron pairs. We have also succeeded in the in-situ scanning tunneling microscope observation for the epitaxial thin films of heavy-fermion compounds for the first time and reveled the suppression mechanism of the superconductivity by nonmagnetic Zn impurity doping.
