Metallic glasses (a) High Fe or Co containing glasses (e.g. Feo.7Po.2Co.i) Low-loss ferromagnetic ribbons for use in transformer cores... 

The formation of metal glasses by rapid cooling was first reported by Paul Duwez and co-workers in the 1960s. They achieved cooling rates of thousands of degrees per second by shooting a fine stream of liquid metal onto a water-cooled copper drum. With the early compositions, cooling rates of about 105 K/s were necessary to prevent crystallization. This limited alloys to thin ribbons or wires. 

There are two principal uses for glassy metals. Because metal glasses have no barriers for domain wall movement they are excellent soft magnetic materials. Thin ribbons have been used for transformer cores since the 1960s. Metallic glasses have very good corrosion resistance and very low damping.
