Abstract

Pocket change A recent paper (Nature 447, 565—568 2007) described the electronic structure of a hole–doped high–temperature copper oxide superconductor in its normal metallic state. The Fermi surface observed in underdoped materials — made up of small pockets — was at odds with that of their overdoped counterparts, and quite unlike that of conventional metals. Now David LeBoeuf et al. use measurements of the Hall effect to show that these structures in the Fermi surface are electron pockets, not the 'hole' pockets suspected. This pocket formation could be a result of an enigmatic symmetry–breaking phase, similar to that seen in some electron-doped copper oxides. The implicated phase seems to be a generic property of the copper oxides, so may be expected to play a central role in shaping the properties of high–temperature superconductors.
