Abstract

While there is increasing evidence for antiferromagnetic (AF) ordering in the Cu-O planes of high-[Formula presented] superconductors, either static or fluctuating, there is no direct evidence so far for the charge stripes that should separate the AF domains. By investigating the optical response of [Formula presented] for [Formula presented] and [Formula presented], we identify strong far infrared peaks whose energy, width, and intensity are consistent with a scenario of charge stripe dynamics in the Cu-O planes.
