    • A fractal structure formed to provide a plurality of regions having mutually different fractal dimensions featuring self-similarity. A fractal structure growth conditions that provide a first fractal dimension during a growth process between a growth starting time and a first time, and is grown by using growth conditions that provide a second fractal dimension lower than the first fractal dimension between the first time and a second time. A phase transition property, e.g. a critical temperature of ferromagnetic phase transition, expressed in the fractal structure, is controlled by adjusting a switching timing of growth conditions. To obtain a higher controllability, the first fractal dimension is set to be larger than 2.7, and the second fractal dimension the be smaller than 2.3.
    • 分形结构,其形成为提供具有彼此不同分形维数的多个区域,具有自相似性。 分形结构生长条件,其在生长开始时间和第一时间之间的生长过程期间提供第一分形维数,并且通过使用生长条件生长,所述生长条件提供第一分形维数低于第一分形维数 第二次。 相变特性,例如 通过调整生长条件的切换时间来控制以分形结构表示的铁磁相变的临界温度。 为了获得更高的可控性,第一分形维数设置为大于2.7,第二分形维数小于2.3。
