Abstract

The high Tc superconducting material YBa2Cu3O7−x has been studied for its absorption in the FIR region. Measurements have been carried out using a Fourier Transform Infrared (FTIR) spectrophotometer at different temperatures above and below Tc. Observed bands are examined in the light of theoretical calculations based on different models. Certain IR absorption bands show screening effects in the measurements below Tc. Experimental values for observed IR bands are compared with the work of other authors and the bands are assigned to different IR active modes of vibration of the material.
