A brief introduction to micromagnetism was given in Chapter 17 of ; it included the description of domains and walls, and the derivation of the Landau—Lifshitz equation. Chapters 1 and 9 of this Volume deal with micromagnetic material which is used in magnetic tapes and disks. This material consists of magnetic particles suspended in a binder which is then painted onto a substrate such as polyester film (for tapes) or aluminum disk.
