A group of Japanese and Russian scientists recently announced the development of a graphene-based material that could improve the storage capacity and density in devices meant for holding data such as hard drives or memory cards. The inclusion of the material does away with the rewrite limit inherent in many existing data storage devices.
Today’s data storage devices have some key limitations. From incorrectly recording a file, the computer’s inability to read the device, or the sheer size the device would have to be in order to record a massive amount of data.
The international research team’s material is said to vastly improve the magnetic memory capacity of such devices by increasing recording density. According to Graphene-info, the material is a combination of graphene and the semi-metallic Heusler alloy, Co2FeGaGe.
Previous attempts to use graphene in magnetic memory storage devices were thwarted, because carbon atoms reacted to the magnetism which affected their properties and performance. Using the Heusler alloy allowed the team to create a thinner sample than previous efforts. It’s hoped their findings will allow data storage devices to hold considerably more data while remaining small in size.
