Faster Data Storage Thanks to Molecular Magnets Containing Rare Earth Materials?

Jülich, 20 October 2016 - Molecular magnets made from metal atoms and organic molecules could one day enable the development of storage media with greater capacity and faster, more energy-efficient information processors. Until now, rare earth metals were regarded as unsuitable for this purpose, as the electrons responsible for their magnetic properties are “hidden” in 4f orbits, which are difficult to access for studies or technical use. Theoretical studies performed in Jülich now explain how strong organic molecules can modify the chemical environment around rare earth metals. As a result, orbits are able to form that unite characteristics of atomic and 5d+4f hybrid orbitals, and are more easily accessible for studies using e.g. scanning tunnelling microscope measurements, or in technical applications.
