Saturation magnetization
The saturation value of magnetization of a ferromagnetic body. The inside of the magnetic body is normally divided into any number of domains, but accompanying increase in the external magnetic field, domain walls may move and magnetization may rotate within domains, so ultimately the magnetic body becomes one domain (single-domain state). If the easy magnetization axis and the external magnetic field direction match, this state is called magnetization saturation and the value of the magnetization at this time is called the saturation magnetization.
