Abstract
Infrared reflectivity spectra of multilayered HgBa2Can−1CunO2n+2+δ (n=2, 3, 4, and 5) are measured. Optical plasma modes associated with the Josephson coupling between CuO2 planes within a multilayer appear below Tc in the c-axis component of the reflectivity spectrum. The result allows for quantitative estimation of the interlayer Josephson coupling strength within a multilayer. It is found that the change of the Josephson coupling strength correlates with the increase of Tc up to n=3 and the subsequent decrease for n≥4.
