Abstract
Infrared ( 20–120 and 900–1100cm−1) Faraday rotation and circular dichroism are measured in high- Tc superconductors using sensitive polarization modulation techniques. Optimally doped YBa2Cu3O7 thin films are studied at temperatures in the range ( 15<T<300K) and magnetic fields up to 8 T. At 1000cm−1 the Hall conductivity σxy varies strongly with temperature in contrast to the longitudinal conductivity σxx which is nearly independent of temperature. The Hall scattering rate γH has a T2 temperature dependence but, unlike a Fermi liquid, depends only weakly on frequency. The experiment puts severe constraints on theories of transport in the normal state of high- Tc superconductors.
