Title: Far-infrared absorption by bulk high- T sub c superconductors using an optically pumped CH sub 3 OH laser

Abstract

We have developed a far-infrared-absorption-measurement method using an optically pumped far-infrared laser. The temperature dependence of the light absorption by high-{ital T}{sub {ital c}} superconductors has been investigated for the photon energy between 7.6 and 17.6 meV in the temperature region between 12 and 160 K. A well-defined transition temperature was obtained from the absorption measurement. With decreasing temperature, the absorption decreased, but did not reach zero even at sufficiently low temperatures.
