Far-infrared investigation of the pseudogap in underdoped Pb2Sr2(Y/Ca)Cu3O8
Abstract
The optical conductivity of underdoped Pb2Sr2(Y/Ca)Cu3O8 has been obtained from 40 to 700 cm-1 via Kramers-Kronig analysis of the c-axis-polarized reflectance measured at temperatures between 10 and 300 K. In the normal state at the lowest and highest frequencies where it is least obscured by a large phonon contribution, the background c-axis optical conductivity of underdoped Pb2Sr2(Y/Ca)Cu3O8 is observed to decrease systematically as the …
