摘要
本文讨论二维Ｃｕ－Ｏ面中ｈｏｌｏｎ引起铁磁极化子的强关联系统的自由能．根据自由能极小时系统稳定的特性，求得铁磁极化子在低温（ｋＢＴ＜＜Ｊｅｆｆ）下的稳定半径为γｆ＝ ａ．并指出铁磁极化子配对引起超导电性的可能性．
This article discusses strong correlative system's free-energy with holon causing ferromagnetic polaron in the two-dimensional Cu-O plane. According to the characteristic that the system is steady when free-energy is the minimum, we calculate ferromagnetic Polaron's radius rf = a when kBT << Jeff, and put forward the probability that pair-ferromagnetic polarons leads to superconductivity.
