Optical properties of thin YBa2Cu3O7 films in the IR region
Konstantinov V. L , Stark S. Yu., Tsidil'kovskii I. M.
The IR reflection spectra of superconducting YBa2Cu307 _ s films deposited on substrates of various materials have been studied. The value of the parameter 2A/kTc found from the experimental results is about 9.5.
