On the peak in the far-infrared conductivity of strongly anisotropic cuprates
Abstract
We investigate the far-infrared and submillimeter-wave conductivity of electron-doped La(2-x)CexCuO4 tilted 1 degree off from the ab-plane. The effective conductivity measured for this tilt angle reveals an intensive peak at finite frequency ( ~ 50 cm-1) due to a mixing of the in-plane and out-of-plane responses. The peak disappears for the pure in-plane response and transforms to the Drude-like contribution. Comparative analysis of the mixed and the in-plane contributions allows to extract the c-axis conductivity which shows a Josephson plasma resonance at 11.7 cm-1 in the superconducting state.
