Ferrogadolinium is an alloy that consists of several elements that have undergone a transition from a liquid to a solid state and have characteristic metallic properties. A number of gadolinium alloys, and in particular an alloy with cobalt and iron, enable the creation of information carriers with an enormous recording density. This is due to the fact that in these alloys special structures are formed, the so-called. CDM - cylindrical magnetic domains, and the size of these domains is less than 1 micron, which enables storage media for modern computer technology to be created with a recording density of up to 9 billion bits per 1 cm2 of media area.
Areas of application:
- As a master alloy, gadolinium iron can be used for grain refining, hardening, and improving alloy performance by improving properties such as ductility and machinability. The gadolinium-iron alloy is also used as a very spacious hydrogen storage and can be used for a hydrogen car engine.
