Abstract
We report measurements of the far-infrared transmission of superconduc ting YBa2Cu3O7-delta thin films from 5 to 200 cm(-1) in fields up to 1 4 T. A Kramers-Kronig analysis of the magnetotransmission spectrum yie lds the magnetoconductivity tensor which is found to be dominated by t hree terms: a London term, a low frequency Lorentzian (omega(1) approx imate to 3 cm(-1)) of width Gamma(1) = 10 cm(-1), and a finite frequen cy Lorentzian of width Gamma(2) = 17 cm(-1) at omega(2) = 24 cm(-1) in the hole cyclotron resonance active mode of circular polarization.
