Abstract
The complex transmission of Y1-xPrxBa2Cu3O7 single crystal thin films has been measured in the range 0.2-1.0 THz using time domain spectrosc opy. The complex conductivity is calculated without using a Kramers-Kr onig analysis. All of the superconducting samples show a peak in sigma (1)(T) below T-c. The underdoped samples show a deviation from 1/(alph a + beta T) behavior above T-c that may be linked with the onset of a spin gap.
