AbstractWe report inelastic neutron scattering experiments on single crystals of superconducting Ba0.67K0.33Fe2As2 (T-c = 538 K). In addition to confirming the resonance previously found in powder samples, we find that spin excitations in the normal state form longitudinally elongated ellipses along the Q(AFM) direction in momentum space, consistent with density functional theory predictions. On cooling below T-c, while the resonance preserves its momentum anisotropy as expected, spin excitations at energies below the resonance become essentially isotropic in the in-plane momentum space and dramatically increase their correlation length. These results suggest that the superconducting gap structures in Ba(0.67)Ka(0.33)Fe(2)As(2) are more complicated than those suggested from angle resolved photoemission experiments.
