Abstract

We report optical spectra of underdoped $BaFe_{1.89}Co_{0.11}As_2$ that hosts both of magnetic and superconducting orders. The temperature dependent evolution of optical conductivity shows finger prints of the magnetic order and the s-wave nature of the superconducting gaps. Careful inspection on the superconducting state reveals that the two orders compete but coexist in the ground state.
