A new generation of experiments on Sr2RuO4

The unconventional superconductor Sr2RuO4 has delighted but mostly confounded its loyal devotees (a number of whom are in this department) for a quarter of a century. Over the past year I have been involved in collaborations with a number of groups world-wide who are performing a new generation of experiments to try and sort out what is going on. The basic idea of is to profit from Cliff Hicks’ invention of new methods of applying uniaxial pressure and extend some of the classic experiments of the 1990s – NMR Knight shift, muon spin rotation, heat capacity and ARPES – to highly strained Sr2RuO4. I will summarise the new findings, most of which are unpublished, and assess where they leave us in terms of the unified understanding that gives select old guys round the world sleepless afternoons.
