Magnetic data storage

In recent years, the growing numbers of publications are concerned with ultra-fine metal oxide structures because of their useful applications as bactericides, adsorbents, energy storage media, magnetic data storage, and ferrofluids and specifically as catalysts [6, 7]. 

Several lanthanide metals can be found in certain types of magnetic data storage disks for computers. Gadolinium, terbium, and dysprosium are among the elements often sandwiched with iron and cobalt in thin layers to make these devices.

Metal nanopartieles have been shown to be important for catalysis, spectroscopy, optoelectronic devices, and magnetic data storage. Successful exploitation of metallic nanopartieles lies in the successful conjugation of their active surface structure. Thus, size and shape play a role in terms of variable surface energy. This becomes paradoxical when surface activity and stabilization are examined both surface activity and particle stabilization need to be controlled. Thus, proper support becomes inevitably a unique choice, which simultaneously can promote surface activity and provide stabilization to the metallic nanopartieles for innumerable applications. Proper support stabilizes metal nanopartieles of different sizes and shapes but not at the cost of surface activity. At this time, only a few achievements are promising. In an analogous fashion, metal oxides, generally transition metal oxides, are robust and are the future material of choice for supports.
