Amorphous ferromagnetic materials

Metallic alloys with an amorphous structure, also known as metallic glasses, are materials in which there is no long-range atomic order.

They correspond to a metastable phase that extends the phase associated with the supercooled liquid and is thermodynamically identical to it.

In particular, these amorphous alloys can be used to manufacture small and medium transformers (25 to 100 kVA) and magnetic components for power electronics.
