Design of high-temperature single-molecule magnets

The volume of stored digital information is increasing exponentially, and the economic and environmental costs could be mitigated by increasing data densities by orders of magnitude. In place of standard storage media, data could potentially be stored in individual molecules on the nanoscale using single-molecule magnets (SMMs). Molecular data storage could dramatically increase data densities, but memory must persist at economically viable temperatures. We have pioneered approaches for designing some of the best-performing SMMs known, and we are now working to understand in more detail the origins of magnetic relaxation (the process by which magnetic information is lost) to further improve magnetic memory in molecules.

Designing molecular spin qubits for quantum information

Of the many potential implementations of quantum bits (qubits), molecular spin qubits are particularly favourable: e.g. they have a low fabrication cost, are perfectly identical and are chemically tuneable. Furthermore, they can be engineered to be robust against magnetic noise and exhibit quantum coherence times rivalling solid state qubits. We are investigating how they can be protected from other environmental degrees of freedom such as vibrational noise, such that they maintain their coherence properties in device-like architectures.

Intramolecular magnetic interactions

We are interested in the fundamental intramolecular magnetic interactions that occur within complexes of d- or f-elements. This work encompasses both measurement and theory, and attempts to find appropriate models or rules that govern such interactions.
