Far-infrared spectra along the c axis in high-Tc superconductors

Abstract Recent studies of infrared spectra along the c axis in high temperature cuprate superconductors are reviewed. The most prominent features are the existence of the plasma resonance in the superconducting state and its absence in the normal state, which are common in most of high-Tc superconductors. The various methods for observing the plasma and the features of these methods are briefly reviewed. The resonance are discussed based on the Josephson-coupled layer model, and the resonance frequencies and the c-axis penetration depth Λ c for the various high-Tc superconductors are summarized.
