Infrared reflectvity of high T/sub c/ oxide superconductors and related crystals

Summary form only given, as follows. The temperature dependence of infrared reflection spectra of ceramics and crystals belonging or related to the family of oxide superconductors is reported in the wavelength range from 1 micron to 1 millimeter. Spectra are simulated with appropriate dielectric function models and results are discussed within the framework of the importance of electron-phonan coupling in oxides.
