Effects of a particle-hole asymmetric pseudogap on Bogoliubov quasiparticles
J. P. F. LeBlanc, J. P. Carbotte, E. J. Nicol
We show that in the presence of a pseudogap, the spectral function in the superconducting state of the underdoped cuprates exhibits additional Bogoliubov quasiparticle peaks at bot…
Static magnetic order of SrAOFeAs (A = Sc and V) revealed by local probes
J. Munevar, D. R. Sanchez, M. Alzamora +10
Static magnetic order of quasi two-dimensional FeAs compounds Sr4A2O6-xFe2As2, with A = Sc and V, has been detected by 57Fe Moessbauer and muon spin relaxation (μSR) spectroscopies…
Electron-boson glue function derived from electronic Raman scattering
B. Muschler, W. Prestel, E. Schachinger +4
Raman scattering cross sections depend on photon polarization. In the cuprates nodal and antinodal directions are weighted more strongly in and symmetry, respecti…
Effect of annealing on the specific heat of optimally doped Ba(FeCo)As
K. Gofryk, A. S. Sefat, M. A. McGuire +6
We report the temperature dependence of the low-temperature specific heat down to 400 mK of the electron-doped Ba(FeCo)As superconductors. We have mea…
Effect of annealing on the specific heat of Ba(Fe1-xCox)2As2
K. Gofryk, A. B. Vorontsov, I. Vekhter +5
We report on the effect of annealing on the temperature and field dependencies of the low temperature specific heat of the electron-doped Ba(FeCo)As for u…
Specific heat across the superconducting dome in the cuprates
A. J. H. Borne, J. P. Carbotte, E. J. Nicol
The specific heat of the superconducting cuprates is calculated over the entire phase diagram. A d-wave BCS approach based on the large Fermi surface of Fermi liquid and band struc…
