Contrasts in electron correlations and inelastic scattering between LiFeAs and LiFeP revealed by charge transport
S. Kasahara, K. Hashimoto, H. Ikeda +3
By using high-quality single crystals, we quantitatively compare the transport properties between LiFeAs and LiFeP superconductors with compensated electron and hole carriers. The…
Microscopic Evidence of Direct Coupling between Magnetic and Superconducting Order Parameters in BaFe(AsP)
T. Iye, Y. Nakai, S. Kitagawa +5
The coexistence of magnetism and superconductivity in the isovalent-P-substituted BaFe(AsP) has been investigated microscopically by P-NMR measurements.…
Extremely strong coupling superconductivity in artificial two-dimensional Kondo lattices
Y. Mizukami, H. Shishido, T. Shibauchi +8
When interacting electrons are confined to low-dimensions, the electron-electron correlation effect is enhanced dramatically, which often drives the system into exhibiting behavior…
Volovik effect in a highly anisotropic multiband superconductor: experiment and theory
Y. Wang, J. S. Kim, G. R. Stewart +7
We present measurements of the specific heat coefficient γ(= C/T) in the low temperature limit as a function of an applied magnetic field for the Fe-based superconductor BaFe(A…
Reply to Comment by Borisenko et al. on article `A de Haas-van Alphen study of the Fermi surfaces of superconducting LiFeP and LiFeAs'
C. Putzke, A. I. Coldea, I. Guillamon +10
Recently, Borisenko et al have posted a Comment (arXiv:1108.1159) where they suggest an alternative interpretation of our de Haas-van Alphen (dHvA) measurements on the superconduct…
Nodeless vs nodal order parameters in LiFeAs and LiFeP superconductors
K. Hashimoto, S. Kasahara, R. Katsumata +7
High-precision measurements of magnetic penetration depth in clean single crystals of LiFeAs and LiFeP superconductors reveal contrasting low-energy quasiparticle excitations.…
A de Haas-van Alphen study of the Fermi surfaces of superconducting LiFeP and LiFeAs
C. Putzke, A. I. Coldea, I. Guillamon +10
We report a de Haas-van Alphen (dHvA) oscillation study of the 111 iron pnictide superconductors LiFeAs with T_c ~18K and LiFeP with T_c~5K. We find that for both compounds the Fer…
Topological competition of superconductivity in Pb/Ru/Sr_2RuO_4 junctions
Taketomo Nakamura, R. Nakagawa, T. Yamagishi +4
We devise a new proximity junction configuration where an s-wave superconductivity and the superconductivity of Sr2RuO4 interfere with each other. We reproducibly observe in such a…
Nesting of electron and hole Fermi surfaces in non-superconducting BaFe_2P_2
B. J. Arnold, S. Kasahara, A. I. Coldea +4
We report detailed measurements of the de Haas-van Alphen (dHvA) effect in BaFe_2P_2 which is the end member of the superconducting series, BaFe_2(As_{1-x}P_x)_2. Using high purity…
Nodal gap structure of BaFe_2(As_{1-x}P_x)_2 from angle-resolved thermal conductivity in a magnetic field
M. Yamashita, Y. Senshu, T. Shibauchi +8
The structure of the superconducting order parameter in the iron-pnictide superconductor BaFe(AsP) (\,K) with line nodes is studied by the angle-r…
