摘要

PROBLEM TO BE SOLVED: To execute information processing, such as information memory, by controlling phase transition, such as ferromagnetic phase transition, without executing heating. SOLUTION: The phase transition is controlled by controlling the fractal dimensions of fractal aggregate over the entire area or locally. The ferromagnetic phase transition temperature of the magnetic particulates arranged to a shape having self-resemblance in a magnetic material is controlled by the fractal dimensions. In the electronic system of a half field confined in the dendrite fractals, the control of Mott transition is executed by the fractal dimensions of the system. Further, the quantum khaos stronger than heretofore is generated by adding a magnetic impurity to the fractal aggregate and the control of Anderson transport is executed through this process.
