Increasing storage density is an important issue for the magnetic recording industry. Magnetic particles only a few nanometers in diameter offer a promising alternative to the media obtained by "etching" to the scale of a few tens of nanometers. The major difficulty lies in obtaining independent particles and keeping their magnetic orientation at room temperature. Collaboration between SPrAM and SP2M overcame all these challenges.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
