Domain wall (magnetism)

A domain wall in the context of magnetism is a boundary that separates different magnetic domains in a ferromagnetic material. ### Key Concepts: 1. **Magnetic Domains**: These are regions within a ferromagnetic material where the magnetic moments of atoms are aligned in the same direction. Different domains can have different orientations of their magnetic moments. 2. **Domain Walls**: When two magnetic domains with different magnetization directions meet, they create a domain wall.
