Resumen:
In principle, a complex assembly of strongly interacting electrons can self-organize into a wide variety ofcollective states, but relatively few such states have been identified in practice. We report that, in theclose vicinity of a metamagnetic quantum critical point, high-purity strontium ruthenate Sr3Ru2O7possesses a large magnetoresistive anisotropy, consistent with the existence of an electronic nematicfluid. We discuss a striking phenomenological similarity between our observations and those made inhigh-purity two-dimensional electron fluids in gallium arsenide devices.
