Far infrared spectroscopy of high-T/sub c/ superconductors at the national synchrotron light source

摘要

We report the first far infrared transmission spectra for micron-thick films of high T/sub c/ rare-earth superconductors such as DyBaCuO, with implications for the superconducting gap. Spectra were obtained at Brookhaven's National Synchrotron Light Source, a new high-intensity, broad-band millimeter to infrared source.
