Research Abstract

Recent topics in the field of ferroelectrics and superconductors were investigated from the point of view of a common quantum fluctuation and phase transition in oxides with the similar Perovskite-like structures; for example, the conditions to derive relaxor ferroelectrics in mixed perovskite oxides, the analysis of fullerene superconductivity related with Cu-oxides high-Tc superconductors.
