ネール壁

Neel wall

[目次：結晶等(結晶構造／材料試料)]

磁極の向きが互いに180°変わる磁区の境界の構造の一種。試料が薄膜のときに現れる磁壁構造で、薄膜に平行な磁化が磁壁内で薄膜面内で回転して隣の磁区につながる。磁壁を含む二つの磁区からの電子回折図形を見ると、二つの磁区からの回折斑点の間に磁壁部分からのアーク状のディフューズな強度が現れる。

"Neel wall" is one type of the boundary structure of magnetic domains whose magnetization directions are antiparallel or different by 180°to each other. This wall is formed in a thin-film specimen. The magnetic dipoles parallel to the specimen surface continuously rotate in planes parallel to the surface at the magnetic wall, and connect to those of the adjacent domain with the opposite magnetization. In a diffraction pattern formed by two adjacent magnetic domains containing a Neel wall, a diffuse intensity arc appears connecting the diffraction spots from the two domains.
