- Magnetic domain wall
- This is a space in the magnetic domain structure of a magnetic body between magnetic domains and in which the magnetic moment of atoms invert continuously and little bit by little bit. When the magnetization directions of neighboring magnetic domains are 90° or 180°, they are called 90° magnetic domain walls and 180° magnetic domain walls. A domain wall at which the magnetic moments rotate around an axis in the direction perpendicular to the boundary surface is a Bloch domain wall and a domain wall at which the magnetic moments rotate around an axis in the surface inside (the thin film thickness direction) seen in a thin film is a Néel domain wall.
