| The layered perovskite metal Sr3Ru2O7 has generated interest because of the discovery of nematic-like electrical transport properties at low temperatures, in the vicinity of a magnetically tuned quantum critical point. They appear to be the result of the formation of a new phase, which can be observed only in the highest purity single crystals, with mean free paths of several thousand angstroms. In recent years, my group has concentrated on understanding this phase and determining its boundaries using thermodynamic probes. In this talk I will review the physics that we believe underlies our observations, and then report on experiments that are currently in progress using a triple axis vector magnet. |
