…In ferromagnetic materials, the overall magnetization is not uniquely determined by the magnetic field; the magnetization for a given magnetic field depends on the previous magnetization state. This phenomenon is called magnetization hysteresis or magnetic hysteresis. Saturation magnetization is the maximum magnetization that a ferromagnetic material can have at a given temperature, and is equal to the magnetization within a magnetic domain, and is called spontaneous magnetization. … *Some of the terminology that mentions "magnetic hysteresis" is listed below.

…強磁性物質では全体としての磁化は磁場に対して一義的に定まらず,ある磁場に対する磁化はそれ以前の磁化の状態がどうであったかによる。この現象を磁化のヒステリシスまたは磁気ヒステリシス(磁気履歴)magnetic hysteresisと呼ぶ。飽和磁化はその強磁性物質がその温度でもちうる最大の磁化で,磁区の中での磁化に等しく,自発磁化spontaneous magnetizationと呼ばれる。… ※「magnetic hysteresis」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
