Magnetic metal glass is a new type of magnetic material, which has a large glass forming ability and good thermal stability, and only requires a very low critical cooling rate to obtain large-size metal glass. Compared with the traditional magnetic materials, magnetic metal glass has more excellent performance, it has high saturation magnetization, low coercivity, high permeability and large magnetostrictive coefficient, and, in its liquid over Cold region with superplasticity, the use of this feature, can be processed into a variety of high-precision complex shape of magnetic devices.
