Raman Evidence for Superconducting Gap and Spin-Phonon Coupling in Superconductor Ca(Fe0.95Co0.05)2As2
Pradeep Kumar, Achintya Bera, D. V. S. Muthu +8
Inelastic light scattering studies on single crystal of electron-doped Ca(Fe0.95Co0.05)2As2 superconductor, covering the tetragonal to orthorhombic structural transition as well as…
Calorimetric study of the superconducting and normal state properties of Ca(Fe1-xCox)2As2
M. Abdel-Hafiez, L. Harnagea, S. Singh +5
We present a calorimetric study on single crystals of Ca(Fe1-xCox)2As2 (x = 0, 0.032, 0.051, 0.056, 0.063, and 0.146). The combined first order spin-density wave/structural transit…
Incommensurate magnetic excitations in superconducting LiFeAs
N. Qureshi, P. Steffens, Y. Drees +8
Magnetic correlations in superconducting LiFeAs were studied by elastic and by inelastic neutron scattering experiments. There is no indication for static magnetic ordering but ine…
Microscopic co-existence of superconductivity and magnetism in Ba1-xKxFe2As2
Erwin Wiesenmayer, Hubertus Luetkens, Gwendolyne Pascua +6
It is widely believed that, in contrast to its electron doped counterparts, the hole doped compound Ba1-xKxFe2As2 exhibits a mesoscopic phase separation of magnetism and supercondu…
Probing the Unconventional Superconducting State of LiFeAs by Quasiparticle Interference
T. Hänke, S. Sykora, R. Schlegel +7
A crucial step in revealing the nature of unconventional superconductivity is to investigate the symmetry of the superconducting order parameter. Scanning tunneling spectroscopy ha…
Pseudogap-like phase in Ca(FeCo)As revealed by As NQR
S. -H. Baek, H. -J. Grafe, L. Harnagea +3
We report As NQR measurements on single crystalline Ca(FeCo)As (). The nuclear spin-lattice relaxation rate as a function o…
