Splitting of resonance excitations in nearly optimally doped Ba(Fe0.94Co0.06)2As2: an inelastic neutron scattering study with polarization analysis

Paul Steffens, C. H. Lee, N. Qureshi +4

Magnetic excitations in Ba(Fe0.94Co0.06)2As2 are studied by polarized inelastic neutron scattering (INS) above and below the superconducting transition. In the superconducting stat…

Effect of Co doping on the in-plane anisotropy in the optical spectrum of underdoped Ba(Fe1-xCox)2As2

M. Nakajima, S. Ishida, Y. Tomioka +7

We investigated the anisotropy in the in-plane optical spectra of detwinned Ba(Fe1-xCox)2As2. The optical conductivity spectrum of BaFe2As2 shows appreciable anisotropy in the magn…

Anisotropy of the in-plane resistivity of underdoped Ba(FeCo)As superconductors induced by impurity scattering in the antiferromagnetic orthorhombic phase

S. Ishida, M. Nakajima, T. Liang +8

We investigated the in-plane resistivity anisotropy for underdoped Ba(FeCo)As single crystals with improved quality. We demonstrate that the anisotropy in resis…

From d-wave to s-wave pairing in the iron-pnictide superconductor (Ba,K)Fe2As2

J. -Ph. Reid, A. Juneau-Fecteau, R. T. Gordon +18

The nature of the pairing state in iron-based superconductors is the subject of much debate. Here we argue that in one material, the stoichiometric iron pnictide KFe2As2, there is…

Anomalous two peak structure in the Angle-resolved Photoemission Spectra of Ba1-xKxFe2As2

T. Shimojima, W. Malaeb, K. Ohgushi +13

The electronic structure near the Fermi level (EF) of Ba1-xKxFe2As2 (BaK122 ; x = 0.2 - 0.7) is studied using laser ultrahigh-resolution angle-resolved photoemission spectroscopy(A…

Orbital-dependent electron correlation effect on the two- and three-dimensional Fermi surfaces in KFe2As2 revealed by angle-resolved photoemission spectroscopy

T. Yoshida, S. Ideta, I. Nishi +14

We have performed an angle-resolved photoemission study of the hole-overdoped iron pnictide superconductor KFe2As2, which shows a low Tc of ~4 K. Most of the observed Fermi surface…
