We propose a comprehensive study of a series of ruthenium based oxides (ruthenates).Understanding strong electron correlation's is one of the outstanding challenges of condensed matter physics. A major barrier to solving this fundamental problem has been the complexity of many materials that exhibit correlated electron behaviour. The ruthenates offer a timely opportunity to study the diversity of the physics in a controlled, systematic manner. Fewer than ten closely related and relatively simple compounds display a wide range of correlated electron ground states: the series includes insulators, heavy fermion metals, ferro - and antiferromagnets and an unconventional superconductor. In many other correlated electron systems of interest, disorder plays a significant role in hindering the quest for understanding. I contrast, the ruthenates can be prepared as high quality, stoichiometric single crystals with extremely long l mean free paths, enabling sensitive experiments such as quantum oscillation studies, which cannot be performed on most other materials. We will perform a systematic investigation of their low temperature properties, involving studies of the quasiparticle spectra and quantum criticality. The programme will lead to much deeper understanding of the factors which control the formation of such diverse low temperature states in strongly correlated electron systems.
