The London penetration depth in single crystals of Ba(Fe_{1-x}Co_x)_2As_2 at various doping levels
R. T. Gordon, C. Martin, H. Kim +7
The London penetration depth has been measured in single crystals of Ba(FeCo)As using the tunnel diode resonator technique. The measured doping lev…
Andreev spectra and subgap bound states in multiband superconductors
A. A. Golubov, A. Brinkman, O. V. Dolgov +2
The theory of Andreev conductance is formulated for junctions involving normal metals (N) and multiband superconductors (S) and applied to the case of superconductors with nodeless…
Possible phase-sensitive tests of pairing symmetry in pnictide superconductors
David Parker, Igor Mazin
The discovery of the new class of pnictide superconductors has engendered a controversy about their pairing symmetry, with proposals ranging from an extended s-wave or "s"…
Interband superconductivity: contrasts between BCS and Eliashberg theory
O. V. Dolgov, I. I. Mazin, D. Parker +1
The newly discovered iron pnictide superconductors apparently present an unusual case of interband-channel pairing superconductivity. Here we show that, in the limit where the pair…
The electronic structure of the NaCoO surface
D. Pillay, M. D. Johannes, I. I. Mazin
The idea that surface effects may play an important role in suppressing Fermi surface pockets on NaCoO has been frequently proposed to expla…
A key role for unusual spin dynamics in ferropnictides
I. I. Mazin, M. D. Johannes
The 2008 discovery of superconducting ferropnictides with Tc~26K-56K introduced a new family of materials into the category of high Tc superconductors. The ongoing project of under…
NMR relaxation rate in superconducting pnictides: extended scenario
D. Parker, O. V. Dolgov, M. M. Korshunov +2
Recently, several measurements of the nuclear spin lattice relaxation rate in the newly discovered superconducting Fe-pnictides have been reported. These measurements…
The challenge of unravelling magnetic properties in LaFeAsO
I. I. Mazin, M. D. Johannes, L. Boeri +2
First principles calculations of magnetic and, to a lesser extent, electronic properties of the novel LaFeAsO-based superconductors show substantial apparent controversy, as oppose…
The origin of a and e' orderings in NaCoO
D. Pillay, M. D. Johannes, I. I. Mazin +1
It has often been suggested that correlation effects suppress the small e_g' Fermi surface pockets of NaxCoO_2 that are predicted by LDA, but absent in ARPES measurements. It appea…
Unconventional sign-reversing superconductivity in LaFeAsO_(1-x)F_x
I. I. Mazin, D. J. Singh, M. D. Johannes +1
We argue that the newly discovered superconductivity in a nearly magnetic, Fe-based layered compound is unconventional and mediated by antiferromagnetic spin fluctuations, though d…
