Description
Summary:A precursor of superconductivity has been searched in the in-plane optical spectra of underdoped ..., in which the previous c-axis optical spectra showed the presence of superconducting carriers at a temperature far above Tc [Uykur et al., Phys. Rev. Lett. 112, 127003 (2014)][Dubroka et al., Phys. Rev. Lett. 106, 047006 (2011)]. By carefully subtracting the normal component from the imaginary part of conductivity s2(...), we found a clear in-plane response of superconducting condensate at the temperature consistent with the c-axis optical data. This confirms that the precursory superconductivity developing with decreasing doping level is an intrinsic phenomenon in the cuprates. (ProQuest: ... denotes formulae/symbols omitted.)
