…If the magnetic field is further increased, the magnetization in each magnetic domain rotates in the direction of the magnetic field, increasing the magnetization. When the magnetizations are antiparallel across a domain wall, it is called a 180-degree domain wall, and when the magnetizations are perpendicular to each other across a domain wall, it is called a 90-degree domain wall. A domain wall close to a right angle can also be included in the 90-degree domain wall. Inside a magnetic domain, the magnetic moments of the atoms are aligned in one direction, but at the domain wall, the direction of the magnetic moments of the atoms changes. … *Some of the terminology explanations that mention "90-degree magnetic wall" are listed below.

…さらに磁場を大きくすると,各磁区内の磁化が磁場の方向へ回転して磁化が増大することになる。 磁壁を隔てて磁化が反平行になっている場合を180度磁壁,磁壁を隔てて磁化が互いに直角になっている場合を90度磁壁と呼び,直角に近い場合も90度磁壁に含める場合がある。磁区の内部では原子の磁気モーメントは一方向にそろっているが,磁壁のところでは原子のもつ磁気モーメントの向きが変わることになる。… ※「90度磁壁」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 |
