Magnetic Domain

A magnetic domain is a region within a magnetic material which has uniform magnetization. This means that the individual magnetic moments of the atoms are aligned with one another and they point in the same direction. When cooled below a temperature called the Curie temperature, the magnetization of a piece of ferromagnetic material spontaneously divides into many small regions called magnetic domains. The magnetization within each domain points in a uniform direction, but the magnetization of different domains may point in different directions. Magnetic domain structure is responsible for the magnetic behavior of ferromagnetic materials like iron, nickel, cobalt and their alloys, ferrites etc. such as the formation of permanent magnets. The regions separating magnetic domains are called domain walls, where the magnetization rotates coherently from the direction in one domain to that in the next domain. The study of magnetic domains is called micromagnetics.

Magnetic Domain - Observing Domains
... There are a number of microscopy methods which can make the magnetization at a surface of a magnetic material visible, revealing the magnetic domains ... Each method has a different application because not all domains are the same ... In magnetic materials, domains can be circular, square, irregular, elongated, and striped, all of which have varied sizes and dimensions ...
