Most of our technology is based on the use of charge, however the electron also has another less well-understood (or exploited) property called spin. The application of this property in conjunction with charge, offers a range of new “spintronic” devices. One of the most important of these applications is in data storage. Molecular nanomagnets are materials with magnetic cores surrounded by an organic matter sheath. These compounds have shown great potential for application in such very high-density data storage devices. To realise this application the properties molecular nanomagnets still need to be suitably tailored. A family of ruthenium-based nanomagnet triangles offer an example of a new approach being taken to obtain nanomagnets with the ideal properties. Neutron spectroscopy can help us understand this new approach and guide future rational design of new molecules.
