Electronic technologies such as computers, mobile phones and tablets have emerged from understanding and manipulation of electronic and magnetic materials. Complex correlated electron materials such as superconductors and magnets provide a challenge for chemists, physicists and materials scientists to discover new materials and ground states that will guide theory and underpin future electronic technologies. The use of extreme physical conditions is very important to electronic materials research. High temperatures and pressures are used to synthesise and crystallize dense new materials with strongly connected atoms, while property measurements at multiple extremes (combinations of high pressure, low temperatures and high magnetic fields) enable the electron correlations to be explored. These methods will be applied to topical materials such as high temperature and exotic superconductors, spintronic materials, magnetic monopoles in spin ices, and topological electronic materials. The proposed Platform grant will enable us to take a more coherent and strategic view of our research. It will ensure that we make the best use of expensive and demanding materials preparation facilities (Walker press for high pressure and temperature synthesis and Czochralski growth of crystals). Measurements at multiple extremes are a particular common interest, and Platform support will enable us to coordinate and integrate the activities of our team of PDRA's who design, build and use pressure cells for electronic transport, magnetization and neutron scattering measurements. It will also enable our PDRA's and students to gain a broader experience and training by working with colleagues with backgrounds in other disciplines.
