Strongly correlated materials are the source of many of the biggest unsolved puzzles in physics and could potentially revolutioniseinformation technology, through robust quantum computation, spintronics or superconductivity. However, these materials lie on theborder between localisation and delocalisation and so small changes in charge, composition and weak interactions can switch amaterial between states: whether metal, insulator or superconductor. Realising target properties therefore requires careful controlover their stoichiometry and interactions. The modularity and directional bonds in magnetic and electronically conducting metalorganic frameworks (MECMOFs) permits design over the interactions and structures impossible in conventional inorganic or organicmaterials. The first examples of MECMOFs with high conductivity and magnetic ordering temperatures have just now been made, butas a new class of materials, our toolbox of methods for MECMOFs lags behind that of conventional strongly correlated materials, inboth synthesis of non-stoichiometric materials and measurement of their quantum properties. In this project, we will use doping withcharge carriers and ligands to transform these first examples of strongly correlated MECMOFs into a new class of quantum materials.Strongly correlated materials have complex orderings, structural orbital and spin, so I will use my expertise in diffraction andspectroscopy techniques to uncover the hidden orders within these materials. We will also develop methods to measure thequantum properties of Doping Induced Strongly COrrelated MOFs (DISCO MOFs), using the power of (in)elastic neutron scatteringand advanced physical property measurements, in field and under pressure. DISCO MOFs will allow us to design in MECMOFs exoticstrongly correlated states, such as unconventional superconductors, heavy fermion states, and quantum spin liquids, able to resolvefundamental problems and produce transformational technologies.
