- W2068631041 abstract "We report the observation of a pseudogap in the $ab$-plane optical conductivity of underdoped Ba${}_{1ensuremath{-}x}$K${}_{x}$Fe${}_{2}$As${}_{2}$ ($x=0.2$ and 0.12) single crystals. Both samples show prominent gaps opened by a spin density wave (SDW) order and superconductivity at the transition temperatures ${T}_{mathrm{SDW}}$ and ${T}_{c}$, respectively. In addition, we observe an evident pseudogap below ${T}^{*}ensuremath{sim}75$ K, a temperature much lower than ${T}_{mathrm{SDW}}$ but much higher than ${T}_{c}$. A spectral weight analysis shows that SDW competes with superconductivity while the pseudogap is closely connected to the superconducting gap, indicating the possibility of its being a precursor of superconductivity. The doping dependence of the gaps is also supportive of such a scenario." @default.
