Research Abstract

The purpose of this research project is to clarify the relationship between fractal dimension (D) and ordering in cooperative phenomena such as magnetic and superconducting transitions by presenting experimental data. The novelty of this research lies in the realization of control of D of given samples and elucidation of their electronic properties. For three years the study has achieved most of the purposes. The followings have been clarified by measurements of the physical properties of samples with various farctal dimensions; the relationship between Neel temperature of CoO and its fractal dimension, and that between critical current density of high-T_C copper oxide superconductors and its fractal dimension. These results are published in scientific journals after patent was applied.
