…Ferromagnetic and ferrimagnetic materials are generally divided into regions with different directions of magnetization (spontaneous magnetization). These regions are called magnetic domains, and their boundaries are called magnetic domain walls. Ferromagnetic materials can be in a demagnetized state, where they have no apparent magnetization, because they may have a magnetic domain structure in which the overall magnetization is cancelled out. … *Some of the terminology used to describe "magnetic domain walls" is listed below.

…一般に強磁性体およびフェリ磁性体はその内部が磁化(自発磁化)の向きの異なる領域に分かれている。この領域のことを磁区といい,その境界を磁壁magnetic domain wallsと呼ぶ。強磁性体が,見かけのうえで磁化をもたない消磁状態になることがあるのは,全体の磁化が打ち消されてしまうような磁区構造をもつ場合があるためである。… ※「magnetic domain walls」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 |
