To date, nanocrystalline alloys are mostly used in form of laminated ribbon for magnetic cores, and nanocrystalline powder SMCs have been seldom used in practice.

When an external magnetic field is applied to a ferromagnetic material such as iron, the atomic domains align themselves with it. Even when the field is removed, part of the alignment will be retained: the material has become magnetized. Once magnetized, the magnet will stay magnetized indefinitely. To demagnetize it requires heat or a magnetic field in the opposite direction. This is the effect t…
