| Research Abstract |
In this study, elastic stiffness of functional superlattice was measured, and relationship among elastic property, function, and interfacial structure was investigated. In Fe/Pt superlattice, it was found that alloy phase existing at the interfaces affects the macroscopic elastic and magnetic properties. On the other hand, in Co/Cu superlattice, elastic property showed unusual behavior that cannot be explained by existing theory.
