Magnetic properties of bulk metallic glasses

The discovery and large scale investigation of rapidly solidified alloys have brought to light, in the last three decades a new scenario in basic and applied magnetism. With a range of composition and microstructural states unavailable to conventional materials, the rapidly quenched alloys have in fact demonstrated unprecented versatile properties, provide unique opportunities in applications and enlarged the domain of physical theories. In this paper, the basic magnetic features of two classes of magnetic bulk metallic glasses, soft and hard magnetic alloys, will be briefly highlighted.
