Superstructures
add to superconducting mystery October 2004
Brief story on two x-ray scattering studies [PRL 93, 157007 and 157008 (2004)] of

While a possible connection with charge stripes had previously
been proposed, the doping dependence of the modulation period is quite
different, and the local displacements are quite large.
