Balancing Act: Evidence for a Strong Subdominant d-Wave Pairing Channel in Ba_{0.6}K_{0.4}Fe_{2}As_{2}

Balancing Act: Evidence for a Strong Subdominant d-Wave Pairing Channel in Ba_{0.6}K_{0.4}Fe_{2}As_{2}

We present detailed measurements of the temperature-dependent Raman spectra of optimally doped Ba_{0.6}K_{0.4}Fe_{2}As_{2} and analyze the low-temperature spectra based on local-density-approximation band-structure calculations and the subsequent estimation of effective Raman vertices. Experimentall...
